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.
What else do I need?
You may need an 11mm Bi Hex drill socket if you do not already, this is how you tighten the fixing
Why do these have a red cap?
Red caps are required for building regulations; however it is always best practice to use red caps with a rooflight anyway, it makes the roof more secure and marks where a rooflight is if the roof gets covered.
