Sargent 68-4951 Rail Assembly – G-Narrow | 80 Series Exit Device Replacement Part

The Sargent 68-4951 is a genuine OEM Rail Assembly (G-Narrow) engineered as a direct replacement component for the Sargent 80 Series exit device. Also referenced by the full part designation 12-55-57, this assembly is factory-matched to Sargent's 80 Series platform, ensuring precise fit, finish, and mechanical integrity without modification. Rail stock size G is sized to fit doors ranging from 43 inches to 48 inches in width, making it the correct selection for standard to wider openings within that door-width range.

When a rail assembly on a commercial exit device becomes worn, bent, or damaged, the entire device can fail to operate correctly. Specifying the correct OEM replacement — rather than an aftermarket substitute — preserves the integrity of the exit device system and keeps the opening compliant with its original hardware specification.
