Hager ECBB1102 NRP 4-1/2" x 4-1/2" Heavy Weight Ball Bearing Hinge
The Hager ECBB1102 NRP is a heavy-duty, full mortise hinge designed for maximum durability in high-traffic commercial environments. Built for heavy-weight doors and high-frequency service, this hinge features a robust .180 gauge steel construction. It is the ideal solution for schools, hospitals, and office buildings where smooth operation and long-term reliability are non-negotiable.
Critical Security with Non-Removable Pin (NRP)
For exterior and outward-swinging doors, standard hinges pose a security risk as the pins can be removed from the outside. The NRP (Non-Removable Pin) feature eliminates this vulnerability. By utilizing a specialized set screw within the hinge barrel—accessible only when the door is open—the Hager NRP hinge prevents intruders from tapping out the pin to remove the door leaf. This makes it an essential component for secure door hardware installations and high-security entryways.
Engineered for Performance
Equipped with four ball bearings, the ECBB1102 ensures nearly frictionless movement, preventing door sag and reducing the strain on the door closer and frame. Compliant with ANSI A8111 standards, this steel ball bearing hinge is finished with a durable plating that maintains a professional aesthetic while providing industrial-grade strength.
