The 4 Hook Clip is made from 1.5mm thick burnished steel plate designed to act as hidden fixings for Wallbarn decking boards that have a central milled profile.
Will fit boards manufactured with a standard side milling profile, the teeth of the clips grip into the grooves at the sides to hold deck boards in place securely without need for top screws or any visible fixings.
The hooks will provide an approximate 6mm gap between each deck board to ensure uniform spacing. These are secured with Wallbarn’s self-tapping stainless steel screw for Wallbarn Aluminium rails/joists or applicable screws for WPC/composite and timber joists.
A Start/End clip “2 Hooks” is also used to secure the first and last board. This 2 Hook Clip is only available in stainless steel.
