National Marker N140467 Steel Broad Door Hinge 3 Inch

Product Description

The NATIONAL MARKER N140467 is a 3-inch square steel broad butt door hinge designed for average-weight door installations. Part of the National catalog 505 series, it features a tight pin construction and a plain steel finish. This hinge is a standard residential and light commercial fastening component installed by carpenters, general contractors, and maintenance technicians during door hanging, replacement, or frame repair work.

Its tight pin design prevents pin removal during normal service, adding a basic level of security. The plain steel finish makes it suitable for painted or primed applications where the hinge face will not be left exposed to moisture long-term.
