McKinney MacPro MPB99 NRP Heavy Weight Hinge | 4-1/2" x 4-1/2" US32D Stainless Steel
The McKinney MacPro MPB99 NRP is an industrial-grade heavy-duty ball bearing hinge designed for high-traffic commercial openings. Meticulously engineered with a robust .180 gauge thickness, this 5-knuckle, full mortise hinge is the ultimate solution for door restoration in demanding environments like hospitals, schools, and high-frequency public facilities. Crafted from premium US32D Satin Stainless Steel, it provides superior corrosion resistance and lasting reliability.
Maximum Security with NRP (Non-Removable Pin)
The NRP (Non-Removable Pin) feature is a critical innovation for modern facility security. 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.
- Vandal Resistance: Designed to withstand rigorous tampering, offering long-term durability and peace of mind without sacrificing architectural aesthetics.
Key Performance & Safety Features
- Heavy-Weight .180 Gauge Steel: Specifically built to support heavy-weight or high-frequency doors, acting as a permanent solution for door edge reinforcement.
