Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-275 is a 3.5-inch stainless steel door hinge designed for interior residential door applications. Built from stainless steel with a steel material base, this hinge features a removable pin that simplifies installation and removal without special tooling. Mounting screws are included, making it a ready-to-install replacement or new-construction component. It is packaged in a stock-pac bag format and sold in a package quantity of 15, making it well suited for contractors working on multi-door projects or service calls requiring several hinges at once.

This hinge is intended for interior residential door installations. The 3.5-inch leaf size is a standard dimension commonly found on residential passage doors, closet doors, and interior panel doors. The removable pin design allows doors to be lifted off the frame without removing the hinge leaves from the door or jamb, which is a practical advantage during trim-out or renovation work. Carpenters, finish contractors, and general tradespeople are the primary installers of this hardware.

Installation is typically performed by finish carpenters or general contractors during new construction or renovation. Power down any electric door hardware before beginning work on the door frame. Use a chisel and mallet to mortise the hinge leaf flush with the door edge and jamb for proper alignment. Follow local building codes for door hardware installation requirements.
