ADAMS RITE 91-0171 Release Extension Lip

The Adams Rite 91-0171 Release Extension Lip is designed for use with Adams Rite electric strikes, including the 7100, 7110, 7111, 7130, and 7140 series. It is the ideal solution for centre-hung doors, thick doors, or any application where the door centerline to jamb edge dimension varies from standard.

This bolt-on extension lip is measured from the edge of the frame to the centre of the release. For existing electric strikes, installation is straightforward: a thin metal membrane in the standard lip can be drilled or punched out, allowing the extension lip to be easily fitted in the field.

These extension lips are available in multiple options, including lengths of 50mm, 57mm, and 63mm, with corresponding manufacturer references (91-0171-05, 91-0171-07, and 91-0171-09) and weights ranging from 50g to 890g. Please choose your required size and specification from the options below.
