Sargent 68-4690 Narrow Rail Assembly for 80 Series Exit Devices — Size F (33" to 36" Doors)

The Sargent 68-4690 (model suffix 12-53-56 F) is a genuine OEM Narrow Rail Assembly engineered as a direct replacement component for Sargent 80 Series exit devices. This assembly carries the F rail stock designation, meaning it is sized to fit doors ranging from 33 inches to 36 inches in width — the most common commercial door width range found in schools, healthcare facilities, offices, and institutional buildings. Sourced directly from Sargent, this is not an aftermarket substitute; it is the same factory-original assembly used in new production, ensuring precise fit, finish, and function with your existing 80 Series hardware.

Institutional Grade Features & Benefits

• Genuine OEM Quality: Manufactured by Sargent to the same specifications as original production parts, eliminating guesswork about fit, tolerances, or finish compatibility with your installed 80 Series exit devices.
• Narrow Rail Configuration: Designed specifically as a narrow rail assembly, making it the correct replacement for 80 Series devices installed on narrow-stile aluminum doors and similar commercial door constructions where a slim rail profile is required.
