Deltana DSB4B10B Square Hinge Ball Bearing Oil Rubbed Bronze

Product Description

The DELTANA DSB4B10B is a 4-inch by 4-inch square door hinge with ball bearings and an oil rubbed bronze finish. 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.

This hinge is appropriate for interior and exterior door applications where a full-mortise, square-corner hinge is required. The 4-inch by 4-inch leaf size suits standard passage and entry doors. The ball bearing mechanism reduces friction and wear on frequently cycled doors, making it a practical choice for high-traffic doorways. The oil rubbed bronze finish coordinates with matching lever sets, rosettes, and other architectural hardware in the same finish family.

Installation Notes

Installation is performed by carpenters or door hardware installers using a chisel and router for mortise preparation. Power down any electric strike or access control hardware associated with the door frame before beginning work. Verify door weight and frequency of use to confirm the hinge size and bearing type are appropriate for the application before installation. Follow local building codes for door hardware requirements on fire-rated or egress doors.
