Cobra® D-Lock, the steps for assembly of your decking boards




Numerous advantages

Improve the life span of your decking

Cobra D-Lock clips are 8mm thick. This thickness isolates the decking board from the sleeper. In this manner, the clip allows for the proper circulation of air and water between the sleeper and decking board.

This is an advantage with regards to traditional fastening systems which press the board against the sleeper.

A fiberglass-reinforced polymer clip

Our clip withstands over 250kg before distortion and over 350kg before breakage. The COBRA D-LOCK structure is designed with numerous reinforcements and is produced in a POM-type polymer material: polyoxymethylene.

With its structure and high crystallinity, POM offers very good physical characteristics: high tensile strength and shock resistance; excellent fatigue strength; very good resistance to chemicals. This material is particularly resistant to extreme temperatures (-30°C to +50°C).

Easy installation with the drilling template.

The Cobra D-Lock is simple to install with the help of the drilling template which comes with the kit. This metallic bracket makes it possible to pre-drill the decking board directly.

The Cobra D-Lock clips are then quickly screwed down with no position errors.

Kit complete with DECKSPACER
 

The Cobra D-Lock comes with 4 Desk Spacers. When installing, the board's moisture content with regards to the air's hygrometry must be taken into account. Refer to DTU 51-4 for additional details.

The boards must have a minimum distance of 4mm so rainwater and small waste can move freely.
