  • What should I use an RED 29mm coloured cap?
    These Red 29mm colour caps are for use with screws that have a 29mm washer, most commonly rooflight screws, they are red by design so that when fitted, if a rooflight gets covered on a roof, it remains visible where that rooflight is when access to the roof is required. This is a requirement for Building Regulations on buildings that have to meet them or HIGHLY recommended otherwise.

  • What other colours are available?
    If your building does not need to meet building regulations, you may use a Clear 29mm cap, however it is recommended to try and spec RED anyway.

  • What size screw will these fit on?
    8mm plain headed screws such as our Woodtek, Light Section and Heavy Duty drill screws which have a 29mm washer designed for GRP box profile sheets.

  • How do these fit on?
    These just push over the top of the screw and will clip over the washer. If you wish to stick these down, it is recommended to use mastic rather than silicone as that will not stick, although this is not a requirement.
