Finishes: No Finish

Briton Part 5000.IP intumescent pack is an essential fire protection accessory specifically designed for the Briton 5400 and 5700 series mortice lock cases. It ensures full compliance with strict fire-safety standards for fire doors. This universal intumescent pack restores the critical integrity and insulation performance of fire-rated doors by expanding when heated, sealing gaps around the lock body, forend, and strike areas, and delaying the passage of smoke and flames during a fire. Certifire approvals highlight that fitting this intumescent pack is necessary to maintain UKCA and CE markings, as well as EN 1634-1 fire test evidence for timber doors up to 2 hours and steel doors up to 4 hours.
