Institutional Grade Features & Benefits
- Genuine Sargent OEM Part: Factory-engineered replacement that meets the same tolerances and material standards as the original assembly shipped with the exit device.
- J Rail Size — 37" to 42" Door Width: The J designation confirms this narrow rail assembly is cut and configured to span doors in the 37-inch to 42-inch width range, providing a proper fit without field modification.
- 80 Series Compatibility: Engineered exclusively for the Sargent 80 Series exit device line, ensuring seamless integration with existing trim, end caps, and device components already installed.
- Narrow Rail Profile: The narrow rail format is suited for doors with reduced top or bottom rail space, common in aluminum storefront and narrow-stile door applications.
- Simplified Maintenance: Drop-in OEM replacement streamlines scheduled maintenance and emergency repair, reducing labor time and minimizing door downtime in high-traffic commercial or institutional openings.
- Part Number Traceability: Dual reference numbers (68-4657 and 16-53-58 J) support accurate procurement across facilities management systems, MRO catalogs, and service records.
