A brown or white plastic door stop fitted with an intumescent fire seal and brush or rubber smoke seal. Available in 2100mm and 1050mm lengths.


– Designed to upgrade normal hollow-core doors and to replace existing wooden door stops, or used in conjunction with fire-rated doors to maintain integrity

– Can be fitted with acoustic seals which also serve as draught and smoke seals

– Provides up to 68 minutes integrity and insulation when used in a fire door

Application Instructions

Remove the backing from the self-adhesive strip on the back edge of the seal, then position and finish with the panel pins supplied.
Can be used for new installations, as a combined surface-mounted doorstop, brush smoke seal and intumescent fire seal. Alternatively the intumescent section can be routed into the door frame lining, with a rebate of 3mm deep x 50mm wide. The standard smoke seal supplied is a 5mm brush. Rubber seals may also be used (see technical data sheet.) This product should be fitted to the most vulnerable doors (including non-fire-rated doors) such as dining room and kitchen. The smoke seal helps to ensure a fire escape route free from smoke and the intumescent seals the gap between the door and frame to inhibit the spread of fire.
