Hager Hinge 1279415NRP Full Mortise Hinge 4x4 Satin Nickel Nrp

Product Description

The HAGER HINGE 1279415NRP is a full mortise, five knuckle, plain bearing hinge with a non-removable pin (NRP) and a satin nickel finish. Standard weight construction suits interior and light commercial door applications where a clean, durable hinge is required. The hinge measures 4 inches by 4 inches and weighs 0.8 pounds. The non-removable pin design adds a layer of security by preventing pin extraction on the hinge side of the door. Licensed carpenters, door hardware installers, and commercial finish contractors are the primary trade professionals who specify and install this hinge.

This hinge is suited for full mortise installation on standard-weight interior or light commercial doors. The 4 inches by 4 inches leaf size is a common specification for hollow metal and wood door frames in residential and light commercial builds. The satin nickel finish coordinates with matching lever sets, closers, and other door hardware on the same opening. Sold individually, making it practical for single-door hardware packages or replacement installations.

Installation Notes

Installation is performed by a licensed carpenter or door hardware installer following the door manufacturer's mortise preparation specifications. Power down any electrified hardware on the opening before beginning work. Use a sharp chisel and a hinge template to ensure a flush, gap-free mortise so the leaf sits flat with no rocking. Follow applicable building and fire-code requirements for hinge quantity and placement on rated door assemblies.
