Deltana DSB45B3 Square Hinge Ball Bearing Bright Brass

Product Description

The DELTANA DSB45B3 is a 4.5-inch x 4.5-inch square door hinge built with ball bearings for smooth, consistent swing and long-term durability under heavy-use conditions. Finished in Bright Brass, it is constructed from solid brass and sold as a pair. The ball bearing design reduces friction at the knuckle, making it well suited for high-traffic doors that cycle frequently. This hinge is typically installed by carpenters, finish contractors, or door hardware specialists working on commercial or upscale residential projects where architectural detail and finish quality matter.

The DSB45B3 fits full-size interior and exterior door applications where a 4.5-inch square hinge is specified. Its Bright Brass finish coordinates with matching architectural hardware sets. The sold-as-pair unit is standard for single-door installations requiring two or three hinges per door leaf. Typical applications include entry doors, office doors, and heavy interior passage doors in both new construction and renovation work.

Installation Notes

Installation is performed by carpenters or door hardware technicians using standard chisels, a drill, and a screwdriver or driver bit. Remove the door from the frame before mortising hinge pockets to the specified leaf dimensions. Ensure both door and frame leaves are fully seated in mortised recesses before driving fasteners to prevent binding. Verify finish compatibility with other door hardware before installation, as Bright Brass is a non-lacquered polished finish that may require periodic maintenance.
