Orca Hardware Commercial Steel Hinge 4" X 4" Square Corner Plain Bearing, Matte Black

If you're replacing hinges on an interior or light-duty commercial door and want something clean, modern, and tough enough for daily use, the Orca Hardware 4"" x 4"" Commercial Steel Hinge in Matte Black is a solid option that’s easy to install—even for first-time DIYers. This hinge features square corners and a plain bearing design, making it ideal for standard doors that don’t require heavy-duty support or self-closing features. It’s perfect for replacing worn-out hinges in residential entryways, offices, utility rooms, or anywhere you want a simple, functional update with a stylish finish. The matte black finish adds a bold, modern edge to your doors and complements black or dark-toned hardware throughout your space. Whether you're updating just the hinges or coordinating them with new knobs and levers, this finish ties the look together in a clean, understated way. Measuring 4 inches by 4 inches, this hinge fits most standard door setups. The square corner design is best for doors that are already mortised with sharp corners (as opposed to rounded ones), and installation is straightforward. If you're replacing an existing hinge of the same size, you can likely reuse the screw holes—just remove the old hinge and line up the new one. Built from durable steel, this hinge is made to last and maintain alignment under regular use. Whether you're refreshing one door or upgrading the look throughout your home, the Orca COM4040-19 hinge delivers reliable performance and sleek, no-fuss style.
