IS8020si 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 can be face-fixed
orfully mortised into 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.
Face-fixed: The seal is fixed to the face of the door bottom using
the long fixing screws provided. (see detailed fitting instructions).
The reversible aluminium top cover plate conceals the fixing screws
and provides an aesthetic, architectural finish. A set of screw-fixed
reinforced nylon end plates ensure longevity of the seal mechanism.
Fully-mortised: When the seal is to be fully-mortised, the seal (minus
the top cover plate) is mounted into a 54mm deep x 22mm wide
machined groove and screw-fixed back into the door stiles via
stainless steel end plates, holding the seal in place.
Semi-rebated: When the seal is to be semi-rebated, the seal
is mounted into a stepped rebate: a 54mm deep x 22mm 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 cast-aluminium end plates provided.
The seal contains a high efficiency mechanism to assist with the closing
force requirements detailed in AS1428/1 (Design for Access and Mobility).
