The Cobra Airspacer shim promotes ventilation between board and joist without affecting the fixing clip action and wood movements. It thus increases the deck's lifespan. 4 board spacers included for joints of 3, 4, 5 or 6 mm. Recycled polyamide, UV, heat and frost resistant. Design that integrates perfectly under Cobra Hybrid clips for easy and quick installation. Limits shear effect on the fixing screw. Compliant with DTU 51.4 requirements.
