Sargent 98-2479 Chassis Assembly for 80 Series Exit Device — LHRB

The Sargent 98-2479 (12-9863) is a genuine OEM Chassis Assembly engineered for the Sargent 80 Series exit device. This core operating component serves as the mechanical heart of the 80 Series panic hardware: when the push bar is pressed, the push rail transfers that force to this chassis, which retracts the latch to allow egress. Specified for Left Hand Reverse Bevel (LHRB) applications, this replacement chassis assembly restores full, code-compliant egress function to 80 Series devices in institutional, commercial, and high-traffic openings.

Institutional Grade Features & Benefits

• Genuine Sargent OEM Part: Manufactured to the exact tolerances and material specifications of the original 80 Series hardware, ensuring reliable, long-term performance in demanding commercial and institutional environments.
• Core Latch-Retraction Mechanism: Directly receives the mechanical force from the push rail and translates it into latch retraction, maintaining the fast, dependable egress action required by life-safety codes.
• Precise Handing — LHRB: Designed and configured specifically for Left Hand Reverse Bevel door applications, eliminating fitment issues and reducing installation time.
• Drop-In Replacement for 80 Series Devices: Restores failed or worn chassis assemblies to factory-spec operation without requiring full device replacement, reducing maintenance costs on existing 80 Series installations.
• Life-Safety Critical Component: Keeping the chassis assembly in proper working order supports compliance with NFPA 101, IBC egress requirements, and ANSI/BHMA standards for panic and fire exit hardware.
