Thermory® black plastic Uni Clips are suitable for decking board profiles with sg and sg2 side grooves. The clip leaves a 6 mm air gap between the decking board and substructure, ensuring better ventilation and preventing timber-to-timber contact, protecting screws from breaking due to shear forces upon board swelling. The operating mechanism of the clip is based on a pressure plate, enabling the wing of the clip to easily enter the board’s side groove. Boards are secured by the pressure from the screw.
