The first harmonic stainless steel clip
for the assembly of any type of WPC decking.

The first harmonic  stainless steel clip  for the assembly of any type  of WPC decking.


Light, made of excellent AISI 316 Stainless Steel, heat treated and rendered Harmonic to absorb all movements of WPC and always be tight to the boards.

Black painted not to be noticed between the joints of the deck, very resistant to screwing and weathering even in extreme conditions. They will be provided with a black polyethylene insert to accomodate the screw and make a quick and straight screwing.

They'll be sent, on request, already equipped with black stainless screws for wpc, or with self drilling black stainless screws, for a significant saving of time in installation.

In a Deck each component is important

As in a chain, where the weakest link determines the resistance, so in a deck a component of mediocre quality may affect the value of an entire investment. The clip is an essential accessory, because, in addition to creating the proper space between the boards, has the task to secure them firmly to the joists of substructure, resisting to the impact with the screws. But it must also have sufficient elasticity to absorb the omnidirectional movements of the boards. It must be made of a noble material, which lasts over the years in all climatic conditions, and must be as hidden as possible.
t-clip is a fundamental component

Differences with other clips

Ordinary Plastic Clips

Ordinary Plastic Clips


Light, enough inexpensive, they often can amortize the movements of the wpc and they are black colored not to be noticed between the slots of the deck.


There is not always the control of the plastic composition and sometimes they break during the screwing. Once pressed they do not have the required strenght to " return" to work against the boards. They fear frost.

Ordinary Stainless Steel Clips

Ordinary Stainless Steel Clips


Generally made of 304 stainless steel, weatherproof and resistant to screwing.


They are rigid, so they do not absorb the wpc movements, on the contrary they hinder them sometimes causing crushing and reduction of the right space between the boards. Once pressed they don't return tight to the boards. They are often suitable for a single type of board. They are almost never black painted and then you notice them between the spaces. They often need to be inserted under the boards causin stress in that point. The cheapest are often of poor quality.

About us

Technical experts in the design and manufacture of wpc flooring , over the years we have analyzed strengths and weaknesses of each component of a deck. We realized the extreme importance of the fastener.

In fact, the wpc is a material subject to elongations and contractions as a function of temperature and the clip should accompany these movements.
Too often it is assumed that a proper space left between the heads of the boards during assembly, is sufficient to keep everything under control. But the wpc in addition to enlongation, widens, and if the clip will not follow these movements, means that it hinders them, or, almost worse, which can lose contact with the side of the boards.
The solution
Then we needed a fastener that was as strong as stainless steel and flexible as plastic. T.CLIP regrouped itself all the advantages of these two materials, eliminating all their defects. It follows the boards in their micro seasonal movements remaining well pressed to their hips.

For a proper mounting of the boards we recommend the following procedure.
A SUGGESTION: preferably use inserts for screws with the long end not to damage the boards.

Insert the screw into the plastic cap

Insert the screw into the plastic cap with a light pressure. The screw will remain well positioned in the hole of the Clip and there will be no need to hold it steady while screwing.

Thighten and block

highten just enough to block the board. A complete screw would put down the front of the clip making complicated the inclusion of the next board.

Insert the new board

Insert the new board well against so that TCLIP is already " working ". Continue as in step 2.
