A heavy duty, automatic door bottom seal, designed for highperformance acoustic door systems., which is fully mortised into the bottom of single action doors. The seal has a spring loaded mechanism which lifts the seal clear of the floor, in a parallel motion as soon as the door is opened.

Pressure against the door jamb on the adjustable brass strike button operates the seal automatically. The seal is mounted into a 43mm deep x 21mm wide machined groove along the underside of the door. The seal is screw-fixed into position through the mounting flanges. Aesthetic, screw-fixed cast-aluminium end plates ensure longevity of the seal mechanism.
