Fire doors are only as effective as the hardware fitted to them, which is why fire door locks must be suitable for use on fire-resisting doors and installed correctly. In this category you’ll find fire-rated mortice locks commonly used on timber fire doors, including sashlocks (latch + deadbolt for handle operation) and deadlocks (bolt-only security locking).
When selecting a lock for a fire door, it’s important to match the door’s requirements as well as the lock measurements. Start by checking the door rating (for example FD30 or FD60), then choose the correct backset and case size to suit your existing mortice pocket and door furniture. Many fire door lock installations also require intumescent protection (such as an intumescent kit/pack) and a compatible keep/strike plate to help maintain the door’s certified performance.
For best practice, always fit fire door locks in accordance with the door set’s certification and the lock manufacturer’s instructions, and look for third-party tested/certified hardware where applicable (e.g., Certifire/BM TRADA or equivalent). Browse the range to find fire-rated lock options that suit your door type, usage, and measurements.
