Pemko 411ARL Automatic Door Bottom

The Pemko 411ARL Automatic Door Bottom is a full-mortise sponge neoprene insert. It has a milled aluminum finish.

The Pemko automatic door bottom consists of an aluminum case that surrounds a movable drop-bar seal. The drop-bar seal is actuated by a plunger that contacts the jamb as the door is closing, forcing the drop-bar to seal down against the floor or threshold.
