Hager ECBB1103 NRP 4-1/2" x 4-1/2" Heavy Weight Stainless Steel Hinge
The Hager ECBB1103 NRP is the definitive solution for high-security, heavy-duty door applications in demanding environments. Constructed from premium stainless steel, this heavy-weight ball bearing hinge is designed for 1-3/4" thick doors subjected to high-frequency service. Whether for a coastal facility, a laboratory, or a high-traffic commercial entrance, the ECBB1103 provides the structural integrity and rust-resistance necessary for lifelong performance.
Maximum Security: Non-Removable Pin (NRP) Technology
Security is a critical factor for outward-swinging doors where hinge barrels are exposed to the exterior. The NRP (Non-Removable Pin) feature utilizes a specialized set screw within the hinge barrel that is inaccessible when the door is closed. This prevents intruders from tapping out the hinge pin to remove the door leaf. By choosing the Hager ECBB1103 NRP, you ensure enhanced security and protection against forced entry through hinge manipulation.
Superior Durability and Corrosion Resistance
This 4-knuckle ball bearing hinge features a robust .180 gauge thickness and four ball bearings to ensure smooth, effortless operation under heavy loads. While the standard Type 304L stainless steel offers excellent rust resistance, this model is also available in Type 316 grade stainless steel for superior protection in highly corrosive areas, such as marine environments or chemical processing plants.
