Measuring 4.5 inches by 4.5 inches, this hinge is sized for substantial commercial and residential doors where a standard-weight hinge would be undersized. The bright brass finish provides a clean, polished appearance suited to architectural door hardware installations. Ball bearing construction reduces friction and wear over the service life of the hinge. Sold as a pair, the S45BBU3 is a common choice for door installations requiring both durability and a refined finish.\u003c\/p\u003e\n\u003cp\u003eThis hinge is appropriate for interior and exterior door installations where heavy-duty swing hardware is specified. Typical applications include solid-core wood doors, heavy panel doors, and commercial entry doors in both residential and light commercial construction. The 4.5-inch square pattern fits standard mortise hinge preps on door edges and frames. Finish carpenters, door and hardware installers, and commercial contractors are the primary trades specifying this hinge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5 inches x 4.5 inches square hinge plate — sized for heavy-duty door applications\u003c\/li\u003e\n  \u003cli\u003eBall bearing construction for reduced friction and extended cycle life\u003c\/li\u003e\n  \u003cli\u003eBright brass finish for a polished architectural appearance\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty rating suitable for solid-core and commercial-weight doors\u003c\/li\u003e\n  \u003cli\u003eSold as a pair — one pair per order unit\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 doors requiring a 4.5-inch square mortise hinge prep with a bright brass finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by finish carpenters or door hardware installers following standard mortise hinge prep procedures.
