The Sargent 68-3099 F Narrow Rail Assembly (Cam Dog) is a genuine OEM replacement part designed specifically for the Sargent 80 Series exit device. Also referenced by part number 68-3099, this assembly is the manufacturer-authentic solution for restoring proper mechanical function to Sargent 80 Series panic hardware installed on commercial and institutional doors.

Sourcing a genuine Sargent OEM replacement assembly ensures that your exit device continues to perform to its original engineering specifications — critical for facilities that depend on reliable egress hardware in schools, hospitals, office buildings, retail centers, and government facilities. Using authentic manufacturer parts rather than aftermarket substitutes helps maintain device integrity and supports ongoing compliance with building and life-safety codes.

Institutional Grade Features & Benefits

• Genuine OEM Part: Manufactured by Sargent to exact original specifications, ensuring a precise fit and reliable performance within the 80 Series exit device platform.
• Correct Rail Stock Sizing (F): The F rail stock designation confirms fitment for door widths from 33" to 36" — select this part when replacing the narrow rail assembly on doors within that range.
• 80 Series Compatibility: Engineered exclusively for the Sargent 80 Series exit device family, eliminating guesswork for maintenance technicians and facility managers performing targeted component-level repairs.
