We offer automatic door bottom seals by National Guard Products with neoprene, silicone, or nylon brush seals that drop down into place beneath the door when in the closed position. Automatic door bottoms may be surface mounted on the side of the door or mortised into the bottom of the door prior to door installation, and are available in clear aluminum, gold, and dark bronze finishes.
Heavy duty automatic door bottoms lift up clear from the floor when the door is swinging or in the open position, and close down tight to create a perfect seal against the floor or threshold when the door reaches the closed position. Automatic door bottoms with a nylon brush are recommended for carpet applications with no threshold provided, and are available with dual actuated functions that work on both the hinge and latch edge.
