Pemko automatic door bottoms consist of an aluminum case which surrounds a movable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop-bar seal down against the floor or threshold. Provides an excellent seal to keep out draft, dust, moisture, insects, fumes, light and sound. Automatic door bottoms seal up to a 3/4″ gap under the door. Surface and semi-mortise application, non-handed. Can be mounted to either wood or hollow metal doors.
