Typical applications
Pressure rubbers are fitted on both sides of the glass inside a clamp or point fixing. They protect the glass edge and surface from metal contact. Handrail seals go inside a clamp-on glass handrail and are glued in place. The 16–17.5 mm seal is installed with anaerobic adhesive inside the fitted handrail.
