The Sargent 68-3780 is a genuine OEM replacement Rail Assembly designed for the Sargent 80 Series exit device platform.

As an authentic Sargent factory part, the 68-3780 ensures proper fit, finish, and mechanical function when restoring or servicing a Sargent 80 Series delayed egress exit device to like-new operating condition.

Institutional Grade Features & Benefits

• Genuine OEM Construction: Manufactured by Sargent to exact factory tolerances, ensuring a direct drop-in replacement that maintains the structural and operational integrity of the original exit device assembly.
• F-Wide Rail Stock (33"–36" Door Width): The F designation confirms this rail assembly spans the full width range for standard single commercial doors, eliminating guesswork during ordering and installation.
