IS8091si 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 which is face-fixed to the
bottom edge of single action doors. The seal has a spring loaded
mechanism which lifts the seal clear of the floor 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 fixed to the face of the door bottom using the fixing
screws provided. A set of rigid push-fit reinforced nylon end plates
ensure longevity of the seal mechanism. An aesthetic, architectural
aluminium cover plate, provides an ‘easy to clean’ surface for
clean-room environments.
The seal contains a high efficiency mechanism to assist with the
closing force requirements detailed in AS1428/1 (Design for Access
and Mobility).
