National Mfg N830-450 3-1/2 in Door Hinge Satin Nickel 3-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-450 is a 3-1/2 inch, 5/8-inch radius door hinge finished in satin nickel, sold in a three-pack with mounting hardware and instructions included. It features a squeak-guard bearing designed to allow doors to pivot silently through their full range of motion. The bearing is rated for noise-free performance over an extended service life and is constructed with a high-strength material claimed to exceed standard steel bearing strength. This hinge uses a surface-mounted installation method, making it accessible for both trade professionals and knowledgeable DIYers working on residential interior or exterior door applications.

The N830-450 is suited for residential door installations where a satin nickel finish and a 5/8-inch radius corner profile are required. The surface-mount design eliminates the need for mortising, which speeds up installation on new construction or replacement projects. The three-pack format is practical for single-door installations, which typically require three hinges per door leaf. Each pack includes the necessary mounting hardware, reducing the need for separate fastener sourcing on the job.
