You can screw or bolt your acrylic to a variety of materials.
If you are attaching to aluminium pool fencing then we recommend you drill a 6mm hole and then use a roofing or tek screw.
If you are fixing the acrylic to timber then a standard timber screw can be inserted through a pre-drilled hole in the acrylic.
The screw should be smaller than the hole to allow for expansion and contraction. Do not overtighten the screw as the acrylic needs to be able to move as it expands and contracts.
