40x40mm & 42.4mm Cap Rail Gasket for 12mm Glass – 19 ft Roll

40x40mm & 42.4mm Cap Rail Gasket for 12mm Glass – 19 ft Roll
Model: GAS-4040.12

The FMF Cap Rail Gasket is the rubber insert that lines the inside of FMF 40 × 40 mm square and 42.4 mm round cap rail and grips the top edge of 12 mm (1/2") glass. It holds the rail firmly in place, cushions the glass and helps keep water out of the rail.

Each 19 ft roll can be cut to length on site, so one roll covers long runs with fewer joins. The gasket is suitable for interior and exterior glass railings.

Key Features

• Secure Grip: Holds the cap rail firmly on the top edge of the glass.

• Keeps Water Out: Helps seal the rail against water.
