Our high-quality automatic door bottoms are made from extruded aluminum and combined with silicone, closed cell sponge neoprene, felt or brush inserts to form a perfect seal. The seal is established when the plunger is depressed against the door frame, stopping the transfer of air, sound and light. When the door is opened, the seal immediately retracts.
All our automatic door bottoms are easy to adjust, and are reversible, making them suitable for both right and left-handed doors. Stainless steel screws are included for assembly, to ensure every component of the product is durable and long-lasting. Some products are designed to be surface mounted or semi-mortised, and others are designed to be mortised into the door. The maximum effective drop is 5/8” (15.9mm) to 11/16” (17.5mm).
Intertek has certified all of our automatic door bottoms, Clean Air Gold, and the majority have been fire rated for up to 1.5 hours. Many finish options available.
