Sargent 68-4127 Chassis Assembly for 80 Series Exit Devices — Left Hand Reverse (LHR)

The Sargent 68-4127 is a genuine OEM chassis assembly engineered for the Sargent 80 Series exit device platform. Handing: Left Hand Reverse (LHR). This core operating component serves as the mechanical heart of the push-rail exit device: when the push bar is depressed, the push rail transfers force directly to this chassis, which retracts the latch to allow egress. Sourced as an authentic Sargent replacement part, the 68-4127 restores factory-level performance and is the correct service component when the chassis mechanism requires replacement on compatible 80 Series units.
