Kilargo IS8090si Automatic Door Bottom Seal

A heavy 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 brass strike button operates the seal automatically

The seal contains a high efficiency mechanism to assist with the closing force requirements detailed in AS1428/1 (Design for Access and Mobility).

This seal is also available with antimicrobial silicone gasket(s).

  • Silver anodised aluminium with grey end plates (or cast aluminium end plates) and grey silicone gasket

Face-fixed: 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.
