Description
Brown Fixing buttons
These come in a pack of 10 and are specific to the thickness of the polycarbonate you have ordered, 10,16,25mm. These are used to fix the middle of the sheets down to the underneath timbers, between the glazing bars, and should be fitted at approx 50cm centres down the rafters. So for example a 4m long piece of poly will need 9 fixings down each timber.
These are PVC and come with the screw and sealing washer on the bottom to stop water ingress into the roofing sheets themselves.
