IS8530si Automatic Door Seal
Automatic door bottom seals incorporate a spring-
loaded mechanism that automatically lowers to seal the gap as the door closes and retracts as it is opened. They are available in either face-fixed,
semi-rebated or fully mortised options.
A heavy duty, automatic door bottom seal, designed for high-
performance 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.
