Hager 1279 NRP US26D 4.0" x 4.0" Full Mortise - Plain Bearing Hinge, Steel with Plated Finish
The Hager 1279 NRP US26D is a security-enhanced Full Mortise Plain Bearing Hinge designed for standard-weight doors in residential and professional settings. Measuring 4" x 4" and finished in a sleek Satin Chrome (US26D), this steel hinge is specifically engineered for doors requiring low-frequency service. The standout Non-Removable Pin (NRP) feature provides a critical layer of protection for outswinging doors, ensuring that your property remains secure against unauthorized entry.
Why Choose the NRP (Non-Removable Pin) Feature?
The NRP technology is a vital innovation for any door where security is a concern. By incorporating a specialized set screw within the hinge barrel, the Hager 1279 NRP prevents intruders from removing the hinge pins to detach the door leaf.
- Enhanced Security: Ideal for exterior doors or sensitive interior areas, the NRP ensures the door cannot be removed from the outside even if the hinges are accessible.
- Optimal for Outswing Doors: In outswing configurations, hinge pins are naturally exposed to the exterior. The NRP feature effectively mitigates this vulnerability.
- Peace of Mind: This design provides long-term reliability and tamper resistance without compromising the clean architectural look of the Satin Chrome finish.
