Built with ball bearings, the hinge reduces friction on high-traffic doors and maintains consistent swing performance over time. At 4.5 inches by 4.5 inches, this hinge is sized for substantial door applications. It is sold as a pair and is suited for installation by door hardware specialists, commercial finish carpenters, and general contractors working on architectural millwork projects.\u003c\/p\u003e\n\u003cp\u003eThis hinge is appropriate for heavy interior and exterior doors in both residential and light commercial settings. The antique brass finish suits traditional and transitional architectural styles. The heavy-duty construction makes it a practical choice for solid-core wood doors and other demanding door assemblies where a standard-weight hinge would be undersized. Each order yields one pair of hinges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5 inches by 4.5 inches square hinge plate for heavy-duty door applications\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction for reduced friction and long service life\u003c\/li\u003e\n  \u003cli\u003eAntique brass finish for traditional architectural compatibility\u003c\/li\u003e\n  \u003cli\u003eSold as a pair per order unit\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty rating suitable for solid-core and high-traffic doors\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 heavy-duty residential and light commercial doors requiring a 4.5-inch square ball bearing hinge in an antique brass finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a finish carpenter, door hardware installer, or licensed contractor.
