National Marker N115451 Screen Door Hinge 3 Inch 2-pack

Product Description

The NATIONAL MARKER N115451 is a 3-inch square corner screen door hinge sold in a 2-pack, designed for light-duty door hanging applications in residential and light commercial settings. This is a button tip, loose pin, unswaged, reversible hinge built to handle full-surface, half-surface, half-mortise, and offset installations where the door and jamb are not flush. Each leaf features countersunk screw holes on both sides for clean, flush fastener seating. The hinge carries a BakEnamel finish available in brass and zinc, providing corrosion resistance suited to screen door exposure. Each pair includes 3/4-inch x 8 flat head screws for a complete install out of the package.

This hinge is intended for screen doors, storm doors, and similar lightweight door assemblies in residential construction or repair applications. The reversible design allows installation on left-hand or right-hand doors without requiring a separate SKU. The loose pin configuration makes door removal straightforward during service or seasonal storage. Carpenters, general contractors, and maintenance technicians are the typical installers for this type of hardware.
