Product Data

How it Works

The high quality automatic mechanism consists of an aluminum case which surrounds a moveable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the door jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold. The mechanism causes the seal to always actuate on the hinge side first, which prevents the seal from skidding along the floor/threshold while the door is being closed. Door hang-up will not occur!
