Sargent 68-4082 Chassis Assembly for AL-12-8828 & GL-12-8828 80 Series Exit Devices — Left Hand Reverse (LHR)

The Sargent 68-4082 is a genuine OEM Chassis Assembly engineered specifically for the Sargent 80 Series exit device. This internal operating component serves as the mechanical heart of the 80 Series panic hardware: when the push bar is depressed, the push rail transfers that force directly to this chassis, which then retracts the latch bolt to allow immediate, code-compliant egress. Handing: Left Hand Reverse (LHR).

The device-model prefix is life-safety critical. The AL- prefix denotes an Alarmed configuration, and the 12- prefix denotes a Fire-Rated device. The GL- prefix denotes a Guarded Latch configuration. This chassis assembly is not interchangeable across different prefix families. Always verify the full device designation before ordering.

Compatible 80 Series Exit Device Models

This chassis is designed for use in the following fully designated Sargent 80 Series models:

Institutional Grade Features & Benefits

• Genuine Sargent OEM Part: Manufactured to the same tolerances as the original factory component, ensuring reliable fit, function, and life-safety performance within the 80 Series exit device system.
• Precise Egress Operation: Transfers push-bar force through the push rail to retract the latch bolt, maintaining smooth, dependable single-motion egress actuation required by NFPA and IBC life-safety codes.
• Fire-Rated Device Compatibility: Verified for use in Fire-Rated (12-prefix) 80 Series configurations, supporting installations where UL fire-rated exit hardware is required.
• Alarmed & Guarded Latch Configurations: Compatible with both the AL- (Alarmed) and GL- (Guarded Latch) device variants, covering a range of security-sensitive institutional and commercial applications.
• Prefix-Specific Engineering: Each chassis assembly is purpose-built for its prefix family; using the correct prefix-matched chassis is essential to maintain device certification, latch integrity, and alarm functionality.
• Correct Handing (LHR): Supplied in Left Hand Reverse handing — refer to the handing diagram included with the listing for installation reference.
• Reduces Downtime: Sourcing a direct OEM replacement chassis minimizes field troubleshooting and callback risk compared to aftermarket alternatives.
