Smoke-Rated Surface-Mounted Bottom Door Seal

Our smoke rated fire door bottom 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, this bottom seal has an aluminium body with self extinguishing PVC rubber coextruded seal and carrier. The item also acts as an acoustic door seal for noise reduction up to 37 decibels.

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 of 3mm and 14mm.

 

The smoke-rated surface-mounted bottom door seals can be cut down to size. While the 330mm and 430mm sizes can be cut down by 20mm and 120mm respectively, all other sizes can be cut down by a maximum of 150mm.
 

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