Sargent 68-4129 Chassis Assembly for 80 Series Exit Devices

The Sargent 68-4129 is a genuine OEM Chassis Assembly engineered as the core operating mechanism for Sargent 80 Series exit devices. When a user depresses the push bar, the push rail transfers that force directly to this chassis, which retracts the latch bolt and allows immediate, code-compliant egress. This replacement chassis assembly restores the fundamental mechanical action of the exit device and is the correct service part for maintaining life-safety hardware in proper working order. Compatible device models include the AL-8510 and GL-8510 (Guarded Latch).
