Sargent 68-4097 Chassis Assembly for AL-8863 & GL-8863 Exit Devices — LHR

The Sargent 68-4097 is a genuine OEM Chassis Assembly engineered specifically for the Sargent 80 Series exit device. This part serves as the core operating mechanism of the exit device: when the push bar is depressed, the push rail transfers that force directly to this chassis, which retracts the latch to permit egress. Designed for left-hand reverse (LHR) applications, the 68-4097 is compatible with the AL-8863 (Alarmed) and GL-8863 (Guarded Latch) 80 Series exit device models. Because device-model prefixes carry critical life-safety distinctions, this chassis assembly is not interchangeable across different prefix variants — always verify the full device designation before ordering.

Institutional Grade Features & Benefits

• Genuine Sargent OEM Part: Factory-engineered replacement chassis ensuring precise fit, reliable operation, and maintained code compliance for your 80 Series exit device.
• Core Egress Mechanism: Directly retracts the latch upon push-bar actuation, forming the functional heart of the exit device and ensuring dependable, life-safety-grade egress performance.
• Prefix-Specific Compatibility: Matched to AL-8863 (Alarmed) and GL-8863 (Guarded Latch) devices — the device prefix is life-safety relevant and this part is not cross-compatible with other prefix configurations.
• AL-8863 — Alarmed Function: The AL- prefix designates an alarmed exit device, meaning the device is equipped with an integral alarm that sounds upon activation of the push bar, providing both egress capability and intrusion/unauthorized-exit deterrence.
• GL-8863 — Guarded Latch Function: The GL- prefix designates a guarded latch configuration, incorporating a latch guard that provides added protection against latch manipulation or tampering.
• Left Hand Reverse (LHR) Handing: Factory-configured for LHR door applications — a handing diagram accompanies this listing for reference.
• Restores Exit Device Performance: Ideal for facilities maintenance, retrofit, and repair programs on existing 80 Series installations, avoiding full device replacement and minimizing downtime.
• Commercial & Institutional Applications: Suited for schools, hospitals, government facilities, office buildings, and any environment relying on Sargent 80 Series panic hardware for code-compliant egress.
