Sargent 68-4118 Chassis Assembly for 80 Series Exit Devices — LHR
The Sargent 68-4118 is an OEM Chassis Assembly engineered as the core operating component for Sargent 80 Series exit devices. This left-hand reverse (LHR) chassis serves as the mechanical heart of the exit device: when the push bar or push rail is depressed, the chassis translates that force to retract the latch bolt and allow immediate egress. Designed and manufactured to Sargent's exacting standards, the 68-4118 is the correct factory-matched replacement or service-part chassis for maintaining dependable panic hardware performance on commercial and institutional doors.
