Smoke-Rated Surface-Mounted Bottom Door Seal

Our smoke rated bottom door seal is designed for face mounted applications. It is operated automatically by pressure against the door jamb on its adjustment block and seals when the door closes and retracts automatically when the door is opened. Suitable for wooden or metal door assemblies and smoke tested on proprietary fire doors and has an aluminium body with self extinguishing PVC rubber coextruded seal and carrier.

The seal can be fitted inside (lock side using bumper provided) or outside of the door (non lock side) and has been tested for durability without failure for fire rated smoke doors up to 200,000 cycles. With a 14mm maximum drop, the seal drops on hinge side before lock side and is suitable for all types of swing doors with a Min/Max Gap: 3mm-14mm, the seal can be cut back by 95mm.

Available in seal lengths: 330mm, 430mm, 530mm, 630mm, 730mm, 830mm, 930mm, 1030mm, 1130mm, 1230mm.
