Built for architectural and door hardware applications, it delivers smooth, consistent swing performance through its ball bearing construction. The oil rubbed bronze finish provides a durable, dark patina suited for period-style and transitional door installations. Sold as a pair, this hinge is installed by carpenters, finish contractors, and door hardware specialists working on residential or light commercial projects where a squared corner profile and a classic finish are specified.\u003c\/p\u003e\u003cp\u003eThis hinge is appropriate for interior and exterior door applications where a full-mortise, square-corner hinge is required.
