The joints of laminated parquet are both the weakest and strong part coverings. A carefully thought-out locking system ensures a tight connection of the slats, easy assembly and, of course, obtaining a smooth, durable floor covering.
In 1979, the Swedish company Perstorp AB (in the future Pergo) introduced a new flooring– laminate. Since the technology was just being developed, the new product did not yet have locking joints or even tongue-and-groove edges. A breakthrough was made in 1994, when Välinges took out a patent for a unique development - the world's first mechanical connection for parquet, parquet boards and laminate flooring.
The actively developing giants of the woodworking industry became interested in innovative technology. The laminate manufacturer Alloc was the first to buy the license, introducing the so-called 1G aluminum lock. The following year, 1995, the management of the Kahrs company became interested in the invention. This largest producer parquet boards, which to this day holds a leading position in the market. The modified connection system is called the “2G lock”. In essence, this is a prototype of a coupling kit for modern name Lock. That is, a connection based on the tongue-and-groove principle, but with a carefully designed compacted profile. When assembling the floor covering with the Lock system, a special elastic adhesive was used.
Diagram of the first locking connections for laminate flooring.
Subsequently, the structure of the connecting elements continues to be refined and at the end of 2001 a patent was published for a locking system in which two adjacent plates are closed at an angle of 45°, and after pressing (snapping) a mechanically tight bond is obtained. It is thanks to this development that the laminate with Click lock, so well known today, is produced. This marks the beginning of the era of glueless joining of floor slabs.
Similar connection kits are intended for implementation in multi-layer thin floor coverings: parquet board, engineered wood, laminated HDF or PVC flooring and others. For traditional parquet, vinyl or LVT tiles, solid board simple tongue and groove joints are used.
Manufacturers of laminated flooring in their advertising especially emphasize the glueless locking system, which allows you to quickly, easily and without problems assemble or disassemble the floor. Another advantage is that special profile shapes form waterproof joints without the slightest gaps. But, in fact, there are the following basic types of laminate locks:
- Tongue-and-groove or Lock.
- Snap or Click.
All the common names like T-Lock, Megalock, Click2Click, Uniclick and others are just replications of the main types with their own modifications. Nothing fundamentally new or unique has been developed yet. Patents for these improvements were issued in order to avoid pirated copying of products from well-known European factories by unscrupulous Asian compilers.
Laminate with an adhesive joining system is no longer produced, although you can occasionally find crafts from Chinese “masters” on sale. Let's consider the most interesting options from such giants as Egger, Quick Step, Balterio, Alloc.
Just Click by Egger
Laminate locks from an Austrian manufacturer are a classic click system. The panels snap into place at an angle of 30-45° on four sides, and a fairly high ridge tenon ensures the joint is tight and the connection is resistant to tensile and bending loads. The coating is available in standard form and complete with Silenzio sound-diffusing underlay. The shape of the tongue and groove remains unchanged.
Uniclic by Quick Step
The development of the Belgian plant is no less interesting. The engineering profile provides the possibility of both classic snapping at an angle and the method of attaching or knocking out planks. This The best decision for newbies.
The lock complex from Unilin is convenient for rooms with a complex perimeter, the presence hard to reach places or various “obstacles” - pipes, podiums, low-mounted radiators, etc.
To understand the essence of the three-variant assembly system, watch the video from the manufacturer Quick Step.
PressXpress by Balterio
Such laminate interlocking connections are called 3G, 4G or 5G. That is, an element is added to the structure of the Click-joint - a plastic “tongue”, aluminum grips or protrusions, which provide improved adhesion and prevent the planks from diverging over time (the formation of longitudinal and transverse cracks). One of the brightest representatives of this group is PressExpress from the Belgian plant Balterio. A well-designed “additive” to the main coupling eliminates even a hint of the appearance of gaps between the lamellas and significantly strengthens the joint area. Thanks to this solution, the finished floor covering will withstand significant weight without the slightest damage.
Let us note one drawback. According to reviews from craftsmen, when reassembled, plastic inserts become more of a nuisance element than an auxiliary one, so they are most often removed with pliers. And to obtain a tight joint, sealing gels or sealing masses are used.
4G and 5G-S Aluminum Locking System from Berry Alloc
Laminate flooring with aluminum locks from Allok is unusual in itself. Being a very successful modification of two basic types of joints, the metal “tenon and groove” increases the reliability of the clutch and speeds up the assembly mechanism. In addition, this scheme allows you to reduce the weight of the floor covering, which is a significant advantage for floors with reduced load-bearing capacity.
According to the manufacturer aluminum profile on both long sides of the plank, supplemented with a stiffening rib, increases the tensile strength of the connection. The limit according to test reports is 1200 kg/linear. m. That is why aluminum locks are used exclusively in floor coverings of class 33-34, intended for areas with heavy foot traffic. The floor covering can be disassembled and reassembled 3 times.
Which laminate lock is better?
Let us dispel the most widespread myth that the best flooring is made from a laminated flooring with a Click lock. In fact, flooring material with any type of interlocking connection is designed in such a way as to ultimately obtain a perfectly smooth surface without protrusions, cracks or squeaks. Service life and build quality depend on:
- availability of original coating from well-known brands;
- professionalism of the installers;
- strict adherence to instructions.
The Lock connection, unlike its analogue, does not stretch as much over time, so the cover with the Lock-lock is more convenient to reassemble. The click coupling is more rigid, but subject to a high density of the slab - at least 750 kg/m 3. Let’s make it easier for our readers to choose – in large shopping centers 85% of the range is laminate with the Click system.
Let's destroy another stereotype. Some craftsmen claim that the click-lock allows you to lay laminate flooring with differences exceeding the permissible 2 mm by 2 linear meters surfaces. We will disappoint such would-be specialists - not a single type of connection is designed to smooth out significant irregularities; an even, solid base is always required. Only in this case will you get a smooth, beautiful and functional floor that will last for at least two decades.

Laminate is one of the most popular floor coverings, and it is not without reason that many people prefer it when renovating an apartment with their own hands, since this material can be laid independently, which minimizes the overall costs of repair work. Today we will look at a process like with a Double clic lock, since such products are produced under the Kronostar brand and are quite popular when renovating a room.
Styling tool
To carry out the work you will need hand saw or a jigsaw, a drill or a hammer drill for installing plinths, a tape measure, a hammer and a pencil, so prepare the tool and put it in a visible place so that you don’t waste time searching for it during work. In order to save money, you can choose a household-grade jigsaw, because it is not burdensome for the repair budget and will completely cope with the task of cutting the floor covering. Modern Double clic laminate lock greatly simplifies the work and does not require large quantity tool, however, this does not mean that the process can be approached “carelessly,” so do not lose concentration when working and mistakes will pass you by.
The floor, note, must be level. If there are significant unevennesses, then we level the floor along the guide beacons, otherwise creaking of the coating and cracks are guaranteed.
Laying the covering
If the installation of the coating will be carried out on concrete base floor, then it is necessary first of all to provide further hydro- and vapor barrier and spread an insulating film. Do not confuse it with a standard underlay - it is rolled out on top of the insulation and ensures normal operation of the floor covering (prevents the laminate from squeaking, etc.).
Then the process itself begins self-installation laminate and the first row of coating is assembled, in which the elements are connected using end locks at an angle of 45 degrees, after which they snap into place. Do not forget that laying the laminate requires a technical distance from the wall of 10 - 20 mm, which will subsequently be covered with a floor plinth - see the video below.
Video
After this, you can begin assembling the second row in a similar way, taking into account the fact that the last sheet of the cut cover of the first row becomes the first in the second row and you must do the same in the future, starting a new row from the remainder of the previous one. After the second row is assembled entirely, it is inserted at an angle into the technical gap of the first and is also latched using the Double clic lock. This way, you get a solid surface that is well-balanced in color and reliable in use.
All that remains is to install the floor plinth and you can enjoy beautiful interiors in the room that he helped achieve, how modern material, as well as high-quality independent installation, which, in principle, did not require much time, but the interior design after the work became much more elegant.
Today there is practically no laminate that is installed using glue. Modern panels are connected to each other using special fasteners, which are locks. This type of laminate assembly has certain advantages:
- floor covering elements are easily connected to each other;
- laminate flooring can be easily disassembled completely or on any required area, while it can be easily reassembled at a new or previous installation location.
Now on the market building materials Each manufacturer offers its floor products with locks of its own design, and claims that its design is the best and has unique advantages. You can consider in more detail how they differ and how they are similar. different types laminate locks.
Regardless of the manufacturer, locks are divided into two large groups, which differ in the principle of installation. The types of locks are:
- Lock type latches;
- collapsible Click type.
Lock type locks
Laminate with a Lock-lock is considered a more affordable modification. It entered the market ahead of its competitor. This model performed well thanks to the drive-type lock. Its configuration is cut milling machine from the body of the main layer of the lamella, which is located in the middle part of the product made of HDF or MDF board. One side of the panel has a shaped “tenon”, the other has a matching “groove”. The groove is made in the form of a comb with fixation. During installation, the tenon is driven into the groove.
To hammer one element into another, a wooden mallet or a metal hammer with a wooden stand is used. You can assemble laminate flooring with such a locking structure yourself, but it is better to trust an experienced professional.
Note! To prevent water from penetrating through the joints between products, it is advisable to treat all types of laminate locks with a sealant.
In addition to their advantages, Lock locks have a disadvantage. When walking on a laminate floor, a load is generated that acts on the joint, causing friction. Over time, the fixing part of the comb is subject to abrasion, which leads to a weakening of the contact between the connected panels. Cracks begin to appear at the lock locations, which will no longer be possible to eliminate.
Click locks
Laminate locks of this type were developed later, and they managed to avoid the disadvantages of their predecessor. Laminate flooring with Click locks can be installed even by an amateur who has carefully read the instructions. Assembly of elements occurs at an angle of 45º and ends with snapping. The big advantage of a particular design is the consistency of the quality of the locking connection during the installation process.
Click locks are guaranteed against the appearance of cracks at the joints of the panels. In fact, quality laminate The joints should not be visible at all. If the flooring elements are connected correctly, the floor should look like one monolithic whole.
High-quality click locks are not subject to deformation loads for a long time and do not allow elements to diverge. The floor retains its appearance even under significant loads. When choosing a laminate class, you need to remember that the planned loads on the surface must correspond to those specified on the packaging.
These locks do not risk anything during repeated assembly and disassembly. And if such processes are allowed in the future, you only need to purchase laminate with Click locks. Large and well-known manufacturers of flooring provide a guarantee in case the floor has to be installed and dismantled up to 4 times.

IN modern world Laminate flooring is popular. A special system for laying laminated panels, which snaps them together with a lock, allows you to update the floor easily and quickly.
The service life of the flooring directly depends on the quality of the locks and compliance with the technology of laying the panels.
Peculiarities
The technology for locking laminate flooring was developed not so long ago, but has already earned the love and recognition of people involved in repairs. There are several reasons for this:
- Laminate flooring locks make the flooring installation process easier. No additional fasteners or glue are needed for installation. The latching device is already built into the panel.
- If the panel is damaged, you can easily replace the broken part. This increases the service life of the laminate.
- The locking system for fastening laminate panels allows you to lay the most accurate floor covering without protruding or depressed areas.
- The sides have a special shape, which, when clicked, connects the panels without gaps and does not allow moisture to pass through. This reduces the likelihood of mold growing under the flooring.
Options and description
First, let's look at basic types locks:
- Locke locks appeared much earlier than the other type and are considered more budget-friendly. This mechanism works on the “tenon and groove” principle, that is, on one side the laminate board is equipped with a tenon with a comb for fixation, and on the other side it is a groove. Installation of lamellas with Lock system is carried out by driving the tenon into the groove cavity using a wooden mallet or a hammer with a rubber striker until the connection is complete. Unfortunately, during operation, the combs wear out due to the load on the panels, so gaps may form in the floor covering.
- Click locks, which are also used to connect lamellas, are considered more modern and produced taking into account past mistakes. The name Click locks comes from the characteristic click that is usually heard when the panels are closed. The technology for producing panels with a click-lock is similar to the previous type. However, the tenon side is made in the shape of a hook, and the groove is designed in such a way as to catch this hook. Assembly of a floor covering with such a fastening system does not require special effort and is produced quite quickly. To do this, the panel with the hook side is inserted into the other with the groove at an angle of 45°. After which the panel should be lowered. Then a click will be heard, indicating the entry of the tenon into the groove.
Unlike the lock system, click locks are not afraid of heavy loads and are also easy to disassemble.
In addition to basic locks, many companies, using their own technologies, produce laminate with patented locks. Among existing proprietary developments can be distinguished:
- Just Click from the Austrian company Egger can be called a classic example of locks with a click system. The panels close at an angle of 30° to 45° along the entire perimeter; due to the high tenon, tight joints are obtained, which makes the laminate resistant to heavy loads. Some Egger just-click slat models come with a special Silenzio underlay that helps soften the sound of footsteps.
- Uniclic is an achievement of the Quick Step company from Belgium. A special feature is that it can be snapped both at an angle and when attaching and even tamping the slats. This variety is suitable for inexperienced users. Laminate with the Uniclik system is perfect for finishing floors in rooms with a non-standard shape, various obstacles and hard-to-reach places - a multi-level floor or a low-lying radiator.
- ProLoc and SmartLock are developments of the Belgian company Prego. The first type is represented by a fastening system of three components, which increases the resistance of the laminate to heavy loads and allows you to repeatedly disassemble and reassemble the floor covering. The second type refers to more simple systems mounts that are easy to mount at any angle and easily carry loads.
- Another company Berry Alloc produces its products in Belgium and Norway, and Norwegian laminate is produced with aluminum locks. The patented names of locking connections from this company come in two types - 4G and 5G-S Aluminum Locking System. These locks successfully combine everything best qualities two main types of locks, and the metal tongue and groove system increases the strength of the fastening and makes the installation process faster.
Aluminum locks allow the use of laminate flooring in areas with high loads and high foot traffic. According to the manufacturer, the panels can be disassembled 3 times and reassembled without losing the quality of the floor covering.
- Also found 5G locks with a plastic insert that resembles a tongue. Distinctive feature This type of lock involves assembling the panels in a horizontal position, which allows even a beginner to lay the covering.
- Snap system for laminated panels T-Lock is a development of the Tarkett company. This type of lock allows you to snap a tenon into the groove of another panel at an angle of 45°, not only along the length of the laminate, but also from its end side. This system is distinguished by its reliability and strength of connection. Dual grip laminate can withstand heavy loads and last a long time. During operation, T-Lock does not wear out, does not break or come apart.
- Another popular slat lock ClickXpress equipped with a rounded bottom from the tongue and groove side, plastic parts not included in the model. The possibility of assembling and disassembling such a coating reaches 4 times.
Which is better?
For a person who is not involved professionally repair work, quite difficult to choose suitable laminate among the variety of lock connections.
According to most experts, flooring with Click locks is considered the most practical design. And although Lock locks are less susceptible to stretching over time and are easier to disassemble when necessary, and the price of such a laminate is more affordable, they are still a more outdated modification. Over time and under heavy loads the connections at the joints wear out, creating gaps between the panels.
The Click system, in turn, guarantees maximum strength of connections during repeated assembly and disassembly without damaging the locking system. Laying such a coating is very simple and quick, even on floors with minor unevenness.
And although you will have to pay for such a laminate more money, but the quality of the coating will remain high for many years.
How to connect correctly?
The method of laying laminated panels and connecting them to each other depends on the type of laminate. Before laying the slats in any case it is necessary to eliminate differences and unevenness of the floor using a screed, and then lay the underlay.
There are two options for connecting panels when installing laminate. The adhesive method, thanks to a special technology, protects the joints between the panels from moisture penetration. Therefore, the lifespan of the flooring is significantly increased. But this method also has many negative aspects. For example, waste additional funds to purchase a special water-free adhesive composition; besides, gluing laminate flooring is always more difficult and takes longer. Warm floors are absolutely incompatible with the adhesive method of laying laminate flooring.
In order to lay laminate flooring in this way, you need to apply glue to the groove part of the panel and insert a tenon into it. Then, using a hammer with a wooden head, you need to press the lamellas together as tightly as possible. Surplus adhesive solution must be cleaned with a cloth. First you need to lay out three rows of slats and wait a few hours for the glue to set. Then you can fill the rest of the room with slats.
It should take at least half a day for the flooring to dry completely.
However, due to the ease of installation, construction stores are increasingly offering laminated panels with different locks. Assembly of laminate with Lock-locks occurs by hammering one panel into another. Most Click mechanisms are connected at an angle, and when the panel is lowered to the floor, the lock closes. If necessary, the panels can also be knocked down using a hammer.
Laminate with a locking connection has approximately the same assembly algorithm. Before laying, you need to measure the width of the room so that at least 5 cm in length remains for the last row. If necessary, you need to shorten the slats of the first row. In addition, you need to leave gaps for thermal expansion.
When laying panels using the adhesive method or using Lock-locks, the panels must be joined first along the length and then along the end side. Click-locks are characterized by gathering the entire row of lamellas at once and attaching it as a whole to the previous row.
Therefore, for a large area of the room it is better to enlist the help of an assistant.
Why does it diverge?
Sometimes even such a flawless floor covering as laminate can fall apart. Then it is necessary to determine the cause of the damage to the coating and, if possible, eliminate it.
The cause of failure of the laminate may be dry air, due to which the panels shrink and crack. To avoid this, you need to constantly ventilate the room, or install a humidifier.
Neglecting the screed before laying the laminate leads to the fact that the laminate on an uneven floor diverges, creaks or sways when walking on it, and the locks become unusable.
If the panel lock breaks very quickly, it may be due to the poor quality of the product. There is no need to chase cheapness and choose models from unknown manufacturers.
Failure to comply with installation technology laminate also often leads to problems with the coating. Often during installation they forget to leave gaps, and when the boards swell, the laminate cracks. Don't forget to clean up construction garbage from the floor, since even a small stone can disrupt the operation of the best quality lock.
The lock of the laminate is the most important indicator of quality; its execution largely determines general form coverings. Having a good lock will allow you to get closer to the answer to the question: “which laminate is better.”
Patented by the Quick-Step concern. The locking system is very convenient when laying laminate flooring in doorways, corners and in confined spaces. The board can be snapped using the standard method, at an angle of 25-30 degrees, or by laying the board completely on the floor, using the tamping method.
Another undeniable advantage is the ability to lay and snap boards both on the left and on the right, which is important in complex room configurations. The boards click into place very easily, with a characteristic clear click. Treatment against moisture penetration is present.
According to the manufacturer, the system allows you to repeatedly disassemble the boards without damaging them. In my fifteen years of practice, the only time I encountered a customer’s desire to remove old laminate and move it to the dacha. In any case, the laminate is deformed during use and takes on unevenness in the floor; assembly in a new place is possible, but it will no longer be of such high quality, even if the boards are numbered. The declared function is useful primarily during normal installation by a novice master, when repeated separation of the boards during the fitting process is inevitable.
After assembly, the surface is perfectly smooth without the slightest difference in height or gaps. A small disadvantage of this type of lock is the ability to diverge along the short side of the boards. Connected with a very small protrusion of the latch at the bottom, visible in the photo.
LockT-Lock and 2-Lock
It was produced and is still available for sale by the Tarkett concern (it is being replaced by a new lock). Feature— a large angle of elevation of the board during installation is not required; an angle of 20-25 degrees is sufficient. T-Lock is well-known, but at the same time quite old, requiring assembly of the entire series. For one person, this is a time-consuming task, and sometimes impossible. At length ordinary room six meters, the slightest shift of any panel at the end joint, left or right, will require dismantling the entire row. Also, transverse joints are often visible,
Moreover, this feature is observed in different collections. This defect is most noticeable in collections of dark tones. During installation, you can feel the moment when the board has settled into place, although not as clearly as with Quick-Step. In our work, in the vast majority of cases, we use a laminate with a thickness of 8 millimeters for longitudinal locks, the protrusion is rather weak - often, when snapping it again, it breaks off. Moisture protection is proprietary - Tech3s.
The 2-Lock lock has a plastic insert, provides high assembly performance, plus the ability to work alone.
Lock - TC'Lock
Lock from TARKETT, which replaced the T-Lock. As sales progress, all laminate collections are transferred to the new lock, and without any increase in price. The old and new lock are not compatible; there will be a difference in height of about 0.4 mm.
The manufacturer claims a tighter connection of the boards, which significantly increases protection from moisture. 
The tensile test showed a result eight times higher than the specified parameters, according to the EN13329 standard, which can significantly reduce the number of chips and divergence of boards. Boxes with a new lock are marked accordingly. From personal experience, laminate with such locks assembles perfectly. Fixation - without any effort, the installation speed significantly increases. Assembly can be done by one person.
Lock -
From the manufacturer Classen. A plastic insert is installed at the end of the board, which allows you to snap the board into place by simply pressing on the board from above. Provides a very strong mechanical connection. Work with a vacuum cleaner! The main advantage is the speed of installation; unlike standard methods, there is no need to assemble one long strip, which allows one person to work comfortably, without outside help. Very high quality factory moisture protection.
Pergo PerfectFold 3.0 locking system
A type of lock with a plastic insert. Very easy assembly process. Assembly can be done without a partner. No additional tool required. Convenience and speed of installation, has reverse side— repeated disassembly leads to breakage of the lock ridges. It must be collected immediately, without errors. One should be wary of “confident masters.” The lock looks similar to the Uniclik system, which entails the temptation to knock something out, knock on it, and so on. The result is inevitably damaged locks.
A characteristic, soft click will notify you of correct installation. Assembly can be done from different sides of the boards, both tongue and groove. Relevant when assembling floors without thresholds.
No complaints were identified during operation.
Lock -Proclick andJustclic
From the manufacturer Egger, good locks, Pro does not require assembling the entire row; the board is pushed down from above with a fist blow. High assembly speed.
Just-clic replaced it. Unlike the old one, it requires complete assembly of the row during installation. The profile of the lock is in the form of an oval, with minimal gaps following the contours of the tenon and groove. Very precise fitting of the lock elements, requires perfect cleanliness inside.
Purely subjectively, I liked the first option more, the fixation, without a pronounced click, although in both cases there are no complaints. The surface is perfectly flat.
Lock -Twinclick
Russian manufacturer Kronospan. Almost indistinguishable from T-lock manufactured by Tarkett. Allows you to assemble laminate flooring only in a standard way, in whole rows, it’s better to work together. The quality is at the level of the average price category, without differences in height and gaps. When assembling, there is no feeling of a clear fixation of the lamella. Enough hard work in doorways, a method for fitting to the door frame by cutting off the lock ridge is relevant in inconspicuous places. With this type of lock it is difficult to achieve high-quality installation using the now widespread “entire apartment without thresholds” method. On well-lit surfaces, all the tricks, in the form of a cut lock, will be noticeable, which can lead to rapid wear of the protruding part.
Locks in inexpensive collections do not hold moisture at all; they must be treated with Click Guard sealant. Today, this is already nonsense, given the cost of the sealant and the labor intensity - it is better to choose an option with a waterproof lock.
Lock -Alloc
From a Norwegian manufacturer, very high quality, lock with aluminum insert, for ordinary apartments does not have any advantages, its main advantage is a strong mechanical connection that can manifest itself in large areas, where a conventional laminate requires the installation of dividing thresholds. Ease of installation and clear fixation are a plus. Price is a minus. Compared to the same Classen, given the huge selection of colors, for small apartment, the purchase can hardly be called advisable.
Conclusions:
This article describes only those locks that our locksmiths work with constantly; there are a huge number of different trade names, but the essence remains the same. Padded adhesive locks are a thing of the past. Modern locks allow you to work without glue and sealants, are quite well designed and reliable, provide high quality and strength. The only difference is the ease of installation.
Contrary to manufacturers' statements about the possibility of laying coatings without the use of additional tools, settling the boards using a block or a piece of lock from another lamella is always required! Easy sampling of gaps must be carried out. .
Taking into account the permissible micron gaps, installation work, for any type of lock, should be carried out only with the use of a vacuum cleaner. Dust removal of the groove under the next row is also mandatory!
Laminate flooring that requires laying in a row, it is advisable to lay it with a partner, alone, it is easy to break the lock, this manifests itself in the form of a gap and a characteristic rise in the transverse joint.
All well-known manufacturers in Russia produce laminate in accordance with GOST or TU, often similar to European standards. As a rule, a difference of up to 100 microns is allowed - this is the thickness of a sheet of “Snow Maiden” paper. Tactilely, such a difference will be felt when held with a fingernail, and will be visually visible, although it is considered the norm.
You should not purchase laminate without moisture protection locks, this is no longer relevant, the difference in price is negligible, and the service life differs significantly.
The craftsmen working for us note the successful design of Uniclik locks from Quick-Step, which allow laying laminate flooring in “difficult places” with minimal damage to the lock, and their experience in using coatings from the manufacturer of the same name allows them to give it an “excellent” rating. The preference is for Belgian-made laminate, with the Russian Quick-Step, with quality, however, not everything is so smooth yet. There is no such ease and clarity of assembly. The Uniclic lock is used by the Kastomonu concern, which produces laminate flooring in Elabuga. The new TC-Lock from TARKETT honestly deserves a “good” rating.
