Laplocks are used to fix a rooflight to a fibre cement roofing sheet, or for stitching fibre cement sheets together.
The laplock will expand when tightened creating a secure watertight seal.
Pre-drilling for the sheets is required.
The laplock can be tightened with a standard 8mm hexagon tek screw adapter.
