Stainless Steel Clips secure tightly and easily into Composite Decking Boards for a hidden connection between boards. Stainless Steel Clips and Screws fit within the grooves of Composite Decking Boards for increased wear and corrosion resistance. Clips provide a hidden join thanks to the absence of a larger T-Clip fastening system. Advise connecting 10 clips for every 3.6 metres of Composite Decking. Pack of 100, Stainless Steel. Screws Included. I ordered too many for a garden project.
