Sargent 68-4119 Chassis Assembly for 80 Series Exit Devices — RHR

The Sargent 68-4119 is an OEM chassis assembly 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 permit egress. This is a Right Hand Reverse (RHR) handing-specific component. It is compatible with the following 80 Series exit device models: AL-8728 (Alarmed) and GL-8728 (Guarded Latch).

Institutional Grade Features & Benefits

• OEM Sargent Component: Genuine factory replacement part ensures precise fit, reliable operation, and full compatibility with existing 80 Series hardware.
• Core Egress Mechanism: Functions as the mechanical heart of the exit device — receives push-bar force and drives latch retraction for smooth, code-compliant egress.
• RHR Handing: Manufactured specifically for Right Hand Reverse door applications; a handing diagram accompanies this listing for installation reference.
• Broad 80 Series Compatibility: Confirmed fit for AL-8728 (Alarmed) and GL-8728 (Guarded Latch) exit device models, supporting both alarmed and guarded-latch configurations in the same platform.
• Simplified Maintenance & Restoration: Replacing a worn or damaged chassis assembly restores full exit device functionality without requiring complete device replacement, reducing downtime and overall maintenance costs.
• Commercial & Institutional Applications: Ideal for schools, hospitals, office buildings, retail facilities, and any commercial occupancy relying on Sargent 80 Series panic hardware for life-safety egress compliance.

Applications

The Sargent 68-4119 Chassis Assembly is the preferred service and replacement part for facilities managers, door hardware distributors, and licensed door hardware technicians maintaining Sargent 80 Series exit devices on RHR doors.
