Sargent 68-4112 Chassis Assembly for 80 Series Exit Devices — Left Hand Reverse (LHR)

The Sargent 68-4112 is a genuine OEM Chassis Assembly engineered for the Sargent 80 Series exit device family. This core operating component serves as the mechanical heart of the exit device: when the push bar is depressed, the push rail transfers force directly to this chassis, which retracts the latch bolt to permit immediate, code-compliant egress. Specified for Left Hand Reverse (LHR) door applications, the 68-4112 is an exact-fit replacement that restores factory-correct operation to your 80 Series panic hardware. Also referenced as the AL-8706 & 13 LHR chassis in Sargent service documentation.
