Cladco Composite Decking Stainless Steel Clips & Screws

"Secure your Decking Boards together with durable, anti-corrosive, stainless steel Screws and T-Clip Fixings. 

By using these T-Clips for fixing your Composite Decking Boards, a 7mm space will appear between the Boards to allow for expansion and contraction.
 
Eight T-Clips per 2.4m Board and 11 T-Clips per 4m Board are recommended."
