National Mfg N830-449 3.5 in Satin Nickel Door Hinge 3 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-449 is a 3.5-inch, quarter-radius satin nickel door hinge designed to allow doors to pivot quietly on one edge during operation. This three-pack features a squeak-guard construction built around a military-grade bearing rated at five times the strength of standard steel, delivering long-term, noise-free performance. The satin nickel finish suits interior residential door applications and is surface-mounted for straightforward installation. Each pack includes mounting hardware and instructions. These hinges are backed by a Limited Lifetime Warranty and are rated for 30 years of noise-free service.

The N830-449 is suited for residential interior door installations where a clean, low-profile hinge is required. The surface-mount design eliminates the need for mortising, making it accessible for both professional carpenters and experienced DIYers. The quarter-radius corner profile is a common fit for standard interior door frames. The satin nickel finish coordinates with matching door hardware in residential settings. This package quantity is sold as 15 units (five three-packs), making it practical for contractors or builders working on multi-door projects.

Use the included mounting hardware and follow the provided instructions for proper alignment. Avoid overtightening fasteners, which can cause the hinge leaf to warp and affect door swing.
