Ball bearing construction reduces friction and wear on high-cycle doors, making this hinge a solid choice for commercial and residential door installations where smooth, quiet operation is required. The antique nickel finish is applied over solid brass construction, providing corrosion resistance and a consistent appearance over time. Sold as a pair, this hinge is designed for professional installation by carpenters, millwork contractors, and door hardware specialists working on interior and exterior door applications.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for standard full-mortise installations on interior passage doors, entry doors, and commercial doors where a 4 inch hinge is specified. The 1\/4 inch radius corner profile fits mortise pockets cut with standard radius corner templates, which is the most common specification in commercial and light commercial door framing. The antique nickel finish coordinates with matching door hardware in that finish family, making it appropriate for architectural hardware packages in hospitality, office, and residential renovation projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall bearing construction for smooth, low-friction operation on high-use doors\u003c\/li\u003e\n  \u003cli\u003e4 inch x 4 inch leaf size suits standard residential and light commercial door applications\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch corner radius compatible with standard mortise pocket templates\u003c\/li\u003e\n  \u003cli\u003eAntique nickel finish over solid brass for durability and consistent appearance\u003c\/li\u003e\n  \u003cli\u003eSold as a pair for a complete single-door hinge replacement or new installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for standard full-mortise door applications requiring a 4 inch x 4 inch hinge with a 1\/4 inch radius corner profile and ball bearing construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified carpenters or door hardware installers using a router or chisel to prepare the mortise pocket on both the door and frame.
