National Mfg N830-225 Satin Brass Door Hinge 4 Inches

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-225 is a 4-inch satin brass door hinge designed for interior residential applications. Constructed from steel, it features a removable pin that simplifies installation and removal during door fitting. The satin brass finish provides a clean, neutral appearance suited to standard interior door hardware. Each unit ships with screws included, reducing the need for separate fastener sourcing. This hinge is a straightforward, trade-grade component handled by carpenters, finish contractors, and residential door installers working on interior swing doors.

This hinge is intended for use on interior residential doors. The 4-inch leaf size suits standard interior door weights and thicknesses common in residential construction and light renovation work. The removable pin design allows the door to be lifted off the frame without removing the hinge leaves from the jamb or door edge, which is useful during door hanging and adjustment. Units are packaged individually bagged and sold in a stock pack quantity of 15 per package, making them practical for multi-door projects or contractor supply stocking.

Installation Notes

Installation is performed by carpenters or finish contractors as part of interior door hanging. Mortise the hinge leaf into both the door edge and door jamb to achieve a flush fit before fastening. Use a chisel and mallet for mortise work and a drill or screwdriver for fastener seating. Ensure the door is properly shimmed and plumb in the opening before final screw tightening.
