This window rubber is suitable for fitting either glass or acrylic into boats, cars, vans etc. It allows for easy replacement of damaged windows. Remember to order the filler strip to hold it in place. To find your required size measure your glass and panel thickness and look up the closest size on the table. The rubber will seal approx -1mm (e.g. 4mm glass will seal in a 5mm gap). It is recommended to bed the rubber in with a silicone sealant.

Gap A and gap B relate to the glass and panel thickness. (The rubber is universal so can be used either way round). The web is the thickness of rubber between gap A and B. This stipulates how much smaller your glass has to be in relation to the size of your aperture.
