Sargent 68-4105 Chassis Assembly for AL-12-8866 & GL-12-8866 80 Series Exit Devices — RHR

The Sargent 68-4105 is a genuine OEM Chassis Assembly engineered specifically for the Sargent 80 Series exit device. This part serves as the core operating mechanism of the exit device: when the push bar (push rail) is depressed, it transfers that force directly to this chassis, which retracts the latch and allows egress. Designed for Right Hand Reverse (RHR) door applications, the 68-4105 is the correct replacement or service chassis for the following 80 Series device designations: AL-12-8866 (Alarmed, Fire-Rated) and GL-12-8866 (Guarded Latch, Fire-Rated).

Important: The device-model prefix is life-safety critical. The AL- prefix denotes an Alarmed configuration; GL- denotes a Guarded Latch configuration; and 12- denotes a Fire-Rated application. This chassis assembly is not interchangeable across different model prefixes. Always verify the full device designation — including prefix — before ordering.
