PATENT PENDING

Developed in response to specific user requirements, our new extended drop automatic door bottom solves two common problems. Its integrated design features a unique sloped top casing designed to slough off rainwater and prevent pooling on top of the ADB housing in exterior applications. It simplifies installation by eliminating the need for adding a separate rain drip part to the door bottom

Providing up to a 1.5 inch drop, deeper than typical ADBs, this unit is also designed to help compensate for drop differentials found in door installations with large gradients or slope conditions on one side of the door. The deep drop can also be useful for exterior installations where floor surfaces may be degraded by weather exposure. The deeper drop allows smooth door function in spite of these conditions, which can otherwise cause door bottoms to drag and stick
