What is a Laplock?
A Laplock is a fixing with a rubber sleeve, designed to be used with a Box Profile Rooflight to secure the overlap on a GRP sheet A Laplock is a fixing with a rubber sleeve, designed to be used with a Box Profile Rooflight to secure the overlap on a GRP sheet.

Why do I need to use a laplock?
It allows for expansion and contraction, if you used a metal fitting such as stitchers, this would crack the GRP sheet around the fixing.

How are they installed?
You pre-drill the sheet with a 7mm hole, you then put the laplock into the hole and tighten the 8mm head, this will expand the rubber sleeve to close and watertight the hole, you then clip the Seala cap over the top to ensure that the fixing is fully watertight.

What else do I need?
You may need an 8mm Magnetic drill socket if you do not already, this is how you tighten the fixing.
