Automatic Door Bottoms Non-handed Surface and Semi-mortice
Description

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.

Features:

  • Works on smooth, hard and uneven surfaces.
  • Easy to install, non-handed and fully reversible.
  • Fire tested to BS476-20 and -22 for 30 and 60 minutes.
  • Reduces maintenance costs.
  • Exceeds Building Regulation and DETR requirements.

Benefits:

  • Ensures staff and patient safety in the event of a fire by maintaining fire integrity of the door allowing safe evacuation.
  • Improves security by protecting against under door gap attack.
  • Saves maintenance costs.
  • Provides an effective barrier against draughts and weather, insects, rodents and other vermin, noise, light and smoke, odours and fumes.
