National Mfg N830-448 3-1/2 in Square Hinge Satin Nickel 3 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-448 is a 3-1/2 inch square satin nickel door hinge designed for surface-mounted applications. It uses a military-grade bearing rated at five times the strength of standard steel, which allows the door to pivot smoothly and quietly on one edge. This squeak-guard construction is rated for 30 years of noise-free operation. The package includes three hinges along with mounting hardware and instructions, making it suitable for both trade installation and knowledgeable DIY work on residential interior or exterior doors.

This hinge is used in residential door installations where a surface-mount square-corner hinge is required. The satin nickel finish suits modern and transitional trim packages. The three-pack format is sized for a standard single door installation. Mounting hardware is included, reducing prep time on the job site. The product is also available in matte black for finish-matching flexibility across a project.
