Medium duty, automatic door bottom seal which can be semi-rebated or 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 strike button operates the seal automatically.

This seal can be face-fixed or semi-rebated to the door
bottom using the fixings provided. When the seal is to be semirebated,
the seal is mounted into a 37mm deep x 13mm wide
machined groove. The screw line is covered by an aesthetic flexible
PVC cover strip.

This seal has a brass adjustment button and injection moulded, push-fit nylon end plates plus a high efficiency mechanism to assist with the closing force requirements detailed in AS1428/1 (Design for Access and Mobility).
