Sargent 68-4083 Chassis Assembly for AL-12-8828 & GL-12-8828 Exit Devices — RHR

The Sargent 68-4083 is a factory replacement chassis assembly engineered specifically for the Sargent 80 Series exit device. This is the core operating mechanism at the heart of the 80 Series touchbar — when the push rail is depressed, force is transferred to this chassis assembly, which retracts the latch bolt and allows egress. Sourced directly from Sargent, a trusted name in life-safety hardware, this part restores original factory performance to your exit device installation. This chassis is Right Hand Reverse (RHR) handing.

Device-model prefix designations are life-safety critical and this chassis is not interchangeable across different prefix families. It is compatible exclusively with the full-designation 80 Series models listed below: AL-12-8828 (Alarmed, Fire-Rated) and GL-12-8828 (Guarded Latch, Fire-Rated). Always verify the complete model number — including prefix — before ordering.

Institutional-Grade Features & Benefits

• Factory OEM Replacement: Genuine Sargent component ensuring dimensional accuracy, proper tolerances, and reliable latch retraction performance identical to the original installation.
• Life-Safety Precision: Designed to meet the exacting demands of fire-rated exit device applications where dependable egress is a code and life-safety requirement.
• Alarmed & Guarded Latch Compatibility: Validated for use in both AL- (Alarmed) and GL- (Guarded Latch) prefixed 80 Series devices, covering specialized security and latch-monitoring applications.
• Fire-Rated Application Ready: All compatible models carry the 12- (Fire-Rated) designation, making this chassis assembly appropriate for use on rated openings where exit device fire listings must be maintained.
• Correct Handing Critical: This chassis assembly is handing-specific — supplied in Right Hand Reverse (RHR). Selecting the correct hand is essential for proper latch engagement and code-compliant operation.
• Prefix-Specific — Not Universal: The AL- and GL- prefix designations are mechanically and functionally significant. Do not substitute this assembly into standard (non-alarmed, non-guarded) 80 Series models.
• Minimizes Downtime: Direct-fit replacement reduces labor time during service calls, maintenance cycles, or fire-door exit device refurbishment projects.
