Briton 377 Double Panic Bolt | Rebated Set | Silver | EN1125

Briton 377 Double Panic Bolt

The Briton 377 double rebated panic bolt set is suitable for pairs of rebated timber non-fire rated and fire smoke doors up to 2500mm high x 1300mm wide per leaf. It is CE marked and comprised of a Briton 376 vertical panic bolt, 378 reversible rim panic latch, and 378DDS double door strike.

The Briton 377 push bar panic exit device is tested to meet EN 1125 standards for panic exit devices, so it is perfect in areas where personnel and members of the public will not be aware of how the exit devices operate in an emergency. Escape doors in public areas, or areas with 60+ occupants, should have hardware fitted that is compliant and tested to this standard, which would include shops, schools, hospitals, and cinemas.
