Supplied in a Clear Anodized Aluminium finish applied to a robust and compact aluminium extruded case with a black neoprene gasket. This ADB seal is fitted with a noise blocking rubber (NBR) gasket to eliminate any noise vibrations, and is activated using automatic drop down through the hinge side, via a heavy duty brass trigger button, which is spring loaded to lift clear of the floor as the door opens. Available in various lengths which can be cut down to suit varied openings. Using a V-leaf spring mechanism, it applies even pressure across the entire door bottom ensuring a perfect seal for years to come.
