McKinney MacPro MPB79 NRP Ball Bearing Hinge | 4-1/2" x 4-1/2" Steel
The McKinney MacPro MPB79 NRP is a high-performance, contractor-grade ball bearing hinge designed for average traffic in commercial construction. Meticulously engineered with a .134 Standard Weight thickness, this 5-knuckle, full mortise hinge is a premier solution for door restoration, offering smooth operation and long-term durability for wood or metal doors.
High-Security NRP (Non-Removable Pin) Innovation
The NRP (Non-Removable Pin) feature is a critical security upgrade for modern door installations. It utilizes a hidden set screw within the hinge barrel that is completely inaccessible when the door is closed. This provides:
- Enhanced Exterior Security: Prevents unauthorized door removal by ensuring the hinge pin cannot be tapped out from the outside.
- Optimal for Outward Swinging Doors: A vital solution for commercial door security on exterior openings where hinge barrels are exposed to the public.
- Tamper Protection: Safeguards against forced entry via hinge manipulation, offering peace of mind for high-security areas.

- Ball Bearing Construction: Features precision-engineered ball bearings that ensure effortless door movement, acting as a permanent solution for door edge reinforcement.
- Reliable Steel Build: Constructed from high-strength steel with professional plated finishes to resist wear and maintain architectural appeal.
- Standardized Alignment: Designed with a template screw hole pattern to ensure fast, accurate installation and easy field replacement.
