McKinney MacPro MPB99 NRP Heavy Weight Hinge | 5" x 4-1/2" Stainless Steel
The McKinney MacPro MPB99 NRP is an industrial-strength heavy weight ball bearing hinge designed for high-traffic commercial openings where security and corrosion resistance are paramount. Featuring a massive .190 gauge thickness, this 5-knuckle, full mortise hinge is the ultimate solution for door restoration on oversized or extra-heavy wood and metal doors. Crafted from high-grade US32D Satin Stainless Steel, it provides a sleek architectural finish while offering superior life-safety performance.
Dual-Layer Security & Durability
This hinge is specifically engineered for high-security environments and coastal or high-moisture facilities:
- NRP (Non-Removable Pin): Features a specialized set screw driven into the hinge barrel that is completely inaccessible when the door is closed. This provides a vital solution for commercial door security by preventing intruders from tapping out the pin to remove the door.
- Corrosion Resistant US32D Finish: The Satin Stainless Steel (630) construction offers maximum protection against rust and oxidation, making it ideal for exterior doors, hospitals, and laboratories.
- Heavy Weight .190 Gauge: Significantly thicker than standard hinges, providing the structural integrity needed to support heavy-duty commercial doors without sagging or alignment issues.
Engineered for High-Frequency Use
The MPB99 NRP is built to withstand the rigors of constant daily operation:
- Ball Bearing Construction: Equipped with high-quality bearings to ensure a smooth, silent swing and long-term reliability under constant use.
- Non-Rising Stainless Steel Pin: Features professional button tips that keep the pin securely in place, preventing it from migrating upward over time.
- Template Screw Hole Pattern: Precision-engineered for exact alignment, ensuring easy installation and rapid field replacement in standard commercial frames.
