Measuring 4.5 inches x 4.5 inches, this hinge features a ball-bearing construction that reduces friction and supports smooth, consistent door operation over years of use. It is finished in oil rubbed bronze, providing a dark, matte appearance that suits traditional and transitional architectural styles. Sold as a pair, this hinge is suited for installation by carpenters, finish contractors, and commercial door hardware professionals working on both new construction and replacement projects.\u003c\/p\u003e\n\u003cp\u003eThe S45BBU10B is appropriate for residential and light commercial interior and exterior door applications where a heavy-duty hinge is required.
