This Surface Mounted Automatic Door Bottom has a solid neoprene, self-extinguishing drop seal that closes beneath-the-door gaps of .5” upon door closure. Anti-squeak rubber lining the interior of the metal housing effectively reduces unwanted noise during use. Door bottom is surface mounted, for easy installation.
About INTUMET Fire Stop Technology: Utilizing Intumet™ Fire Stop intumescent material which expands when heated to prevent the spreading of fire. Fire, smoke, and air infiltration rated. Door Gasket is fitted with FS3003 INTUMET™ material. For more information, see Understanding Intumescent Fire Stop Material.
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 frame jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold. The plunger requires low closing force to actuate the drop-bar seal.
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! This door bottom is rated for 5 million cycles.
Installation guide and screws provided. Screws are colored to coordinate with door hardware. To determine length needed, see How to Measure for an Automatic Door Bottom.
