Effective sealing of under-door gaps.
Providing an effective barrier against; draughts, rodents, noise, light, smoke, odours and fumes, Automatic Door Bottoms also improve security by protecting against under door gap attack at a vulnerable position beneath the door leaf. Activated by the opening and closing action of the door, they employ low-force, which does not conflict with lock/ latch/ closer operation and do not require costly electrical connection or threshold obstruction to operate. They are self-levelling in the closed position.
