This is a stainless DECK clip that you can use as a replacement to the standard plastic clips.
You use one clip on every joist where the board intersects a joist so around 15 clips per board is needed.
By using this clip you can make your gaps smaller between the boards to around 4.2mm.
The clips are stainless then painted black so that you don't get any brown stains through the lift of the deck and the black makes it blend inside the shadows of the deck more.
The price is for the deck clip and screw and 1 drill driver per 100 screws
By default we supply you screws to drill into timber joists. If you need self drilling for metal then let us know.
