Our universal Cobra® D-LOCK invisible fastening system is adapted to all types of square-edged deck boards, made of wood or composite wood, 90 to 150 mm wide, and at least 20 mm thick.
Preferably, joists should be 70 mm wide.
The kit has everything you will need to install your deck. One kit corresponds to a 4 m² surface area for an average centre-to-centre distance of 50 cm between joists and 140 mm wide boards.
Structurally designed with many reinforcements, Cobra® D-LOCK is manufactured with POM-type polymer materials: polyoxymethylene. Thanks to its structure and high crystallinity, POM offers very good physical characteristics: high resistance to traction and impacts; excellent resistance to fatigue; very good resistance to chemical agents. This material displays excellent resistance to extreme temperatures ranging from -30°C to +50°C.
COBRA® D-LOCK clips are 8 mm thick. This thickness separates the deck board from the joist. Thus, the clip enables good circulation of air and water between the joist and the deck board. This is an advantage with regards to the traditional fastening system, which flattens the board against the joist.
Our clip resists over 250 kg before warping and more than 350 kg before rupture.
Many tests were conducted by ICAM under scientific conditions. The Cobra D-Lock clip is extremely resistant and guarantees great stability.
The Cobra® D-LOCK is very simply installed using a drilling template included in the kit. This metal square makes it possible to do pre-drilling directly on the deck board. Cobra® D-LOCK clips are then very easily screwed in, without positioning errors.
Here are the 4 steps of installation and the use of different components provided in the kit:
1 - Place the start clip against the joist, leaving an 8 mm clearance from the wall and screw it with two 4 x 245 mm stainless steel screws.
2 - Using a square, trace a mark on the board in order to position the start clip on it. Mark two drill points with the square.
3 - Drill holes with a 3 mm diameter wood bit, then screw in the start clip and the standard clip on the deck board with 4 x 25 mm stainless steel screws.
4 - Flip the board, and insert it in the start clip until it stops.
5 - Using the drilling template, on the second board, trace the positioning mark of the two clips, and pre-drill holes in staggered rows as shown in the figure.
6 - Flip the board, and insert it in the first board.
Use a DECKSPACER® provided in the kit to ensure a 4 mm minimum clearance between boards.
7 - Screw in the clip with a 4 x 40 mm stainless steel screw
First, the drilling template is fastened to position the Cobra D-Lock clips
Flip the deck board
Place the deck board against the one previously installed
With DeckSpacer board spacers, you can adjust the board to ensure Building Codes compliant installation
