Sargent 28-0111 Chassis Cover for 3828 / 80 Series Exit Devices

The Sargent 28-0111 is a genuine OEM chassis assembly designed for the Sargent 80 Series exit device line. Also referenced as the 3828 Series Chassis Cover, this replacement part serves as the core operating chassis of the exit device. When the push bar is depressed, the push rail transfers that force directly to this chassis, which retracts the latch bolt to allow safe, unobstructed egress. Sourcing an exact OEM replacement chassis ensures the mechanical integrity and code-compliant performance of your 80 Series panic hardware installation.

Institutional Grade Features & Benefits

• Genuine OEM Sargent Part: Manufactured to the same tolerances as the original factory component, ensuring a precise drop-in fit for 80 Series exit devices with no modification required.
• Core Egress Mechanism: Functions as the central operating chassis — the push rail transmits force from the push bar directly to this assembly, which in turn retracts the latch and releases the door for egress.
• Maintains Device Reliability: Replacing a worn or damaged chassis restores consistent, smooth latch retraction and preserves the dependable operation that high-traffic commercial and institutional openings demand.
• 80 Series Compatibility: Engineered specifically for the Sargent 80 Series exit device family, making it the correct replacement for facilities already standardized on Sargent panic hardware.
• Reduces Downtime: Having the correct OEM chassis assembly on hand minimizes door hardware downtime during service calls, keeping exit doors operational and life-safety egress paths unimpeded.
