Description:

Features: the Nylon T clip measures 35 x 18 mm, the middle raised part measures 35 x 9 mm with a thickness of 5mm, which means it can provide 5mm-spacing between deck boards while fixing deck boards in place. Installation: firstly, align and install the first row of hidden fasteners over the center of joists but do not tighten the fasteners completely. Make sure the wings remain level with the joists so the next board can fit into the previous board correctly. Repeat this step and install remaining deck fasteners likewise. You can only fully tighten all the screws once all the boards are in place.
