Sargent 68-3678 Chassis Assembly for 80 Series Exit Device

The Sargent 68-3678 is a genuine OEM chassis assembly — also referenced as the MD-12-8600 chassis pack — designed specifically for the Sargent 80 Series exit device. This core operating component is the mechanical heart of the push rail system: when the push bar is depressed, the push rail transfers that force directly to this chassis, which retracts the latch bolt and permits egress. Replacing a worn or damaged chassis restores proper, code-compliant operation to your 80 Series device without requiring a full exit device replacement, making it the preferred solution for facility maintenance teams, locksmiths, and door hardware professionals performing targeted exit device repair.

Institutional Grade Features & Benefits

• Targeted Replacement Solution: Allows maintenance of existing 80 Series exit devices at component level, reducing downtime and total cost of ownership compared to full-device replacement.
• Designed for 80 Series Compatibility: Engineered exclusively for the Sargent 80 Series exit device line, ensuring proper mechanical engagement with existing push rails, cases, and trim.
