Sargent 68-4124 Chassis Assembly for AL-8710 & GL-8710 — 80 Series Exit Device, Left Hand Reverse (LHR)

The Sargent 68-4124 is an OEM replacement Chassis Assembly engineered for the Sargent 80 Series exit device line. This core operating component serves as the mechanical heart of the exit device: when the push bar is depressed, the push rail transfers that force directly to this chassis, which retracts the latch bolt to permit egress. Specified for Left Hand Reverse (LHR) applications, the 68-4124 is the correct chassis for restoring reliable panic-hardware function on worn or damaged 80 Series units. Sourcing a genuine Sargent chassis assembly ensures dimensional accuracy, proper latch engagement, and continued code-compliant operation.

Institutional Grade Features & Benefits

• OEM Sargent Component: Manufactured to the same tolerances as the original factory part, ensuring a true drop-in fit within the 80 Series exit device housing without field modification.
• Core Latch-Retraction Mechanism: Receives push-rail force from the touch bar and converts it into latch retraction — the fundamental egress action of the exit device.
• LHR Handing: Configured specifically for Left Hand Reverse door applications; a handing diagram accompanies this listing for field verification.
• Restores Device Performance: Replacing a worn or damaged chassis returns the exit device to proper operating condition, extending the service life of the overall 80 Series unit.
• Broad 80 Series Compatibility: Fits the AL-8710 (Alarmed) and GL-8710 (Guarded Latch) exit device models within the Sargent 80 Series family.
• Reduced Downtime: A targeted replacement of this single assembly avoids the cost and lead time of replacing the entire exit device.

Applications

The Sargent 68-4124 chassis assembly is the appropriate replacement part for facility maintenance teams, door hardware distributors, and institutional locksmiths servicing Sargent 80 Series exit devices on commercial and institutional doors. Typical installations include schools, healthcare facilities, office buildings, and any high-traffic egress door where panic hardware uptime is critical. Always verify door handing (LHR) before ordering.
