Sargent 68-4080 Chassis Assembly — 80 Series Exit Device (LHRB)
The Sargent 68-4080 is a factory-replacement Chassis Assembly engineered for Sargent 80 Series exit devices. This is the core operating mechanism of the exit device: when the push bar (push pad) is depressed, the push rail transfers that force directly to this chassis, which retracts the latch to permit egress. Handing is Left-Hand Reverse Bevel (LHRB). Sourcing the correct OEM chassis ensures the exit device functions as originally designed — maintaining reliable, code-compliant egress performance without the guesswork of aftermarket substitutions.
Institutional-Grade Features & Benefits
- OEM Sargent Component: A genuine Sargent part built to the same tolerances and materials as the original factory-installed chassis — ensuring fit, function, and longevity.
- Core Latch-Retraction Mechanism: Serves as the mechanical heart of the 80 Series exit device, converting push-bar force into reliable latch retraction for smooth, consistent egress operation.
- Correct LHRB Handing: Configured specifically for Left-Hand Reverse Bevel applications — selecting the proper hand is essential for correct latch engagement and egress function.
- 80 Series Compatibility: Designed exclusively for the Sargent 80 Series exit device family, delivering a direct-fit replacement that requires no field modification.
- Restoration of Original Performance: Replacing a worn or damaged chassis restores the exit device to its original operating specification, supporting ongoing life-safety and code compliance at the door.
Applications
The Sargent 68-4080 Chassis Assembly is the appropriate replacement part when the existing chassis on a Sargent 80 Series exit device is worn, damaged, or otherwise requires service. Typical installations include commercial and institutional doors — schools, healthcare facilities, office buildings, and public assembly occupancies — where Sargent 80 Series panic hardware is already deployed on LHRB-handed doors.
