The Cobra® Hybrid 8-18 clip is a bi-material fastener in matt black to avoid light reflections. Thanks to its 304 stainless steel hooks, it holds your deck boards firmly against the joist. It's quick and easy to install. Thanks to its polypropylene base, there's no need for board spacers, and the Cobra® clip cuts the time needed to build your deck by at least 30% compared with conventional screw installation. Only one screw is needed per clip, and thanks to its self-drilling head, a simple bit (supplied with the clips and screws) is all you need to install the Cobra® clip on the joist without pre-drilling.
The Cobra® 8-18 clip is part of the Cobra® Hybrid range of clips:
1. Cobra® 7-22 clip for bamboo and termo-treated wood decking
2. Cobra® 8-18 clip for composite decking
3. Cobra® 8-25 clip for hardwood decking
The Cobra® Hybrid 8-18 clip is compatible with composite wood and thermo-modified wood deck boards, for installation on wood and aluminium joists.
The wall thickness of the aluminium joist must be at least 2 mm.
1 - Stainless steel screw: Torx pattern for comfort and precision
2 - Clip with claws: 6 claws (3 on each side to hold the blade firmly)
3 - Stainless steel blade: AISI 304, 30 mm wide and 1.20 mm thick
4 - Hollow structure to absorb the movements of the composite wood
5 - Self-drilling point for fixing in wood or aluminium
6 - Polypropylene body: black anti-UV with a width of 6 mm

The Cobra Airspacer wedge promotes ventilation between the board and the joist without affecting the action of the fixing clip or the movement of the wood.
Its customised design fits perfectly under the hollow base of the Cobra Hybrid clips, making installation quick and easy.
The Airspacer helps to limit the shearing effect on the fixing screw.
STEP 1. Fix the Start/End clips to the end of the joists, then insert the first board. |
STEP 2. Insert the Hybrid clips in the board’s groove without screwing them down, then place the next board in touch with the clip’s base. |
STEP 3. Screw on the Hybrid clips, while holding the boards on either side to ensure a perfect perpendicular fixing. |
STEP 4. Repeat the operation and finish with the Start/End clip to fix the last board. |
The use of clamps is highly recommended. It facilitates and optimizes the clips installation, enabling fast and precise screwing of several boards in a row.
To join the two boards together, it is essential to double the joist so that two separate clips can be fitted at each end of the board.
The maximum distance between two joists is 40 centimetres.
The Cobra® Hybrid clip is universal. It can be screwed onto all your joists, whether wood or aluminium, using a high-performance screw. A unique clip designed to suit all decking projects.
The hooks are made from 304 stainless steel. This austenitic stainless steel is commonly used in tooling to guarantee the hardness of the clip, ensure that the board is held firmly against the joist and control board expansion.
Our design office registered this "Hybrid" clip model made from two complementary materials in order to take advantage of their intrinsic characteristics. The clip and its screw resist extreme temperatures, insects, chemicals, chlorine, frost and humidity without oxidising.
Tear strength varies according to the type of joist: 320 kg on exotic wood joists, 135 kg on softwood joists and 205 kg on aluminium joists.
Beware of projects in "polluted" environments. For projects less than 50 m from a coastline or in confined, poorly ventilated areas with a constant saline atmosphere, please consult us.
The Start/End clip or the Start and End clip can be used in addition to avoid any visible screws on the decking.
Alternatively, Cobra® stainless steel WPC coloured head screws can be used.

A special bit with an elongated head for screwing (or unscrewing) between the two blades is supplied with the fitting. This is a major advantage when you need to replace a defective boards or access the cables under your decking without having to dismantle the whole structure. Here are the steps to follow:
1. Unscrew the clips
2. Spread the clips on the ends
3. Remove the old boards
4. Place the new boards
5. Replace the clips
6. Screw in the new boards
