McKinney MacPro MPB68 NRP Heavy Weight Hinge | 4-1/2" x 4-1/2" Satin Chrome
The McKinney MacPro MPB68 NRP is an industrial-strength ball bearing hinge designed for high-traffic openings in commercial construction. Meticulously engineered with a robust .180 gauge thickness, this heavy weight steel hinge is a premier solution for door restoration in demanding environments such as schools, hospitals, and high-frequency public facilities. Its 5-knuckle, full mortise design provides the structural integrity required for heavy-duty doors under constant physical stress.
Maximum Security with NRP (Non-Removable Pin)
The NRP (Non-Removable Pin) feature is a critical security innovation for modern facility management. It utilizes a hidden set screw within the hinge barrel that is completely inaccessible when the door is closed. This provides:
- Tamper-Proof Protection: Prevents unauthorized removal of the door by ensuring the hinge pin cannot be tapped out from the outside.
- Essential for Outward Swinging Doors: A vital solution for commercial door security on exterior-facing doors where the hinge barrel is exposed to the public.
- Security & Peace of Mind: Designed to withstand rigorous tampering attempts, safeguarding against forced entry through hinge manipulation.
Key Performance & Safety Features
- Heavy-Duty Steel Construction: Built specifically to support heavy doors with high-frequency usage, acting as a permanent solution for door edge reinforcement.
- Smooth Ball Bearing Operation: Features high-quality bearings to ensure silent, effortless movement, making it a mandatory choice for doors equipped with automatic door closers.
- UL Fire Rated: Rigorously tested and UL listed (3-hour) for use on fire-rated door assemblies, ensuring full compliance with NFPA 80 and life-safety codes.
- ANSI/BHMA A156.1 Compliant: Corresponds to industry-standard ANSI A8111 (Steel), adhering to recognized benchmarks for structural durability and functional performance.
