A heavy duty, automatic door bottom seal designed for high performance acoustic door systems. This seal can be face-fixed , semi-rebated or fully mortised into the bottom edge 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.

Face-fixed: The seal is fixed to the face of the door bottom using the long fixing screws provided. (see detailed fitting instructions). A set of glass-filled, nylon end plates ensure longevity of the seal mechanism.

Semi-rebated: When the seal is to be semi-rebated, the seal is mounted into a stepped rebate: a 44mm deep x 21mm wide machined groove on the side of the door to which the seal will be positioned. The seal can be screw-fixed into position and fitted with the castaluminium end plates provided.

Fully-mortised: When the seal is to be fully-mortised, the seal is mounted into a 44mm deep x 21mm wide machined groove and screwfixed back into the door stiles via the cast-aluminium end plates, holding the seal in place.
