Sargent 28-2409 Chassis Assembly for 80 Series Exit Devices — New Style, Less Cover

The Sargent 28-2409 is a genuine OEM chassis assembly (less cover, new style) engineered as the core operating mechanism for Sargent 80 Series exit devices. Also referenced as the 28-2409 12-20/30 Chassis Assembly, this replacement part restores the mechanical heart of a panic hardware unit: when the push bar or push rail is depressed, the chassis translates that force into latch retraction, enabling safe and reliable egress. If your 80 Series exit device exhibits sluggish, inconsistent, or failed latch retraction, replacing the chassis assembly with this factory-specified component is the correct repair path.

Institutional Grade Features & Benefits

• Genuine Sargent OEM Part: Manufactured to the same tolerances and specifications as the original factory-installed chassis, ensuring proper fit and function within the 80 Series exit device lineup.
• Core Egress Mechanism: Serves as the primary operating chassis that converts push-bar force into latch retraction, maintaining code-compliant, reliable egress performance.
• New Style Design: This is the current-generation chassis assembly — the updated new-style format — ensuring compatibility with current 80 Series production hardware without the need for additional modification.
• Less Cover Configuration: Supplied without the cover plate, making it the correct selection when only the internal chassis mechanism requires replacement and the existing cover is being retained or sourced separately.
• Precision Replacement for Reduced Downtime: Drop-in compatibility with the Sargent 80 Series means faster service, reduced labor time, and restored exit device operation without full-unit replacement.
• Ideal for Commercial and Institutional Door Hardware Maintenance: Suited for facility managers, door hardware distributors, locksmiths, and service technicians maintaining exit devices on commercial, institutional, or high-traffic openings.
