Aluminum Finish Automatic Door Bottom 36″ Commercial Medium-Duty Seal

The Aluminum Finish Automatic Door Bottom 36″ Commercial Medium-Duty Seal is designed to provide dependable, automatic sealing performance for commercial door applications. Built to fit 36″ door openings, this unit measures 36-1/2″ in length with an overall height of 1-13/16″, delivering full bottom-edge coverage. The satin aluminum finish offers a clean, professional appearance while providing corrosion resistance and long-term durability.

This mechanically actuated automatic door bottom features an internal carrier bar with a vinyl insert that drops from a concealed cavity when the door closes, creating a tight seal against the threshold. When the door opens, the seal retracts automatically, preventing drag and making it ideal for use with carpeted interiors.

Constructed from durable aluminum, this medium-duty automatic sweep is supplied with a frame actuator protector plate and is field reversible for either door hand. It effectively blocks drafts, dust, moisture, and noise infiltration, helping improve energy efficiency and overall interior comfort.
