Description
This automatic door bottom is specifically designed to create the best sound seal possible for normal sound levels. The aluminum casing is fitted with a self-extinguishing, closed-cell sponge neoprene or solid neoprene insert which serves as its primary seal. Additionally, the interior of the aluminum anodized casing is fitted with rubber for extra protection. The mechanism used in this ADB is of the highest quality and has been tested for over 5 million openings and closings! The rubber used in this ADB is not cheap vinyl or EPDM rather it is long-lasting neoprene.
