Sargent 68-2454 Chassis Pack — 80 Series Exit Device Chassis Assembly (LHRB)

The Sargent 68-2454 is a chassis assembly (chassis pack) engineered as the core operating mechanism for Sargent 80 Series exit devices. When the push bar is depressed, the push rail transfers that force directly to this chassis, which retracts the latch bolt to allow immediate, code-compliant egress. This replacement or service chassis is handed Left Hand Reverse Bevel (LHRB) and is compatible with the fire-rated 80 Series models 12-8706 and 12-8713. It is the same factory-spec chassis used in original Sargent 80 Series production, making it the correct choice for restoring full exit device functionality without replacing the entire device.

Institutional Grade Features & Benefits

• OEM-Grade Chassis Assembly: Factory-specification internal chassis designed and manufactured by Sargent to match original 80 Series exit device build tolerances.

• Correct Handing (LHRB): Supplied in Left Hand Reverse Bevel handing — refer to the handing diagram accompanying this listing for door preparation guidance.
