  • What is a Laplock?
    A Laplock is a fixing with a rubber sleeve, This version comes with a RED Seala Washer and Cap, it is designed for corrugated profile GRP such as Iron Profile, Profile 3 and Profile 6.

  • 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.

  • 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.

  • 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
