Product Description

The NATIONAL MARKER N830335 is a 3.5-inch square corner door hinge sold in a 3-pack, designed for interior residential door installations. Constructed from steel, this hinge features a removable pin for straightforward removal and reinstallation during service. The white finish suits standard interior door frames and pre-hung door assemblies. Mounting hardware is included, reducing the need for a separate fastener run. This hinge is a direct replacement for worn or damaged units on residential interior doors and is sized to fit standard door frame mortises.

It is suited for standard-weight interior passage doors, closet doors, and bedroom doors in residential construction and renovation projects. The 3-pack format supports single-door installations that require two or three hinges per door. The white finish aligns with common interior trim color schemes. Carpenters, general contractors, and skilled property maintenance technicians typically install this hardware during new construction or door replacement work.
