Sargent 68-2335 Chassis Pack for 80 Series Exit Device — LHRB

The Sargent 68-2335 Chassis Pack (also referenced as the 12-8863 Chassis Pack) is an OEM-replacement chassis assembly engineered specifically for the Sargent 80 Series exit device. This core operating component sits at the heart of the exit device mechanism: when the push bar is depressed, the push rail transfers that force directly to this chassis, which retracts the latch bolt to permit egress. Designed for Left Hand Reverse Bevel (LHRB) applications, this chassis pack is a precision-fit solution for restoring or maintaining reliable panic-hardware performance on fire-rated door assemblies.
