Deltana DSB55B15A Square Ball Bearing Hinge 5x5 Antique Nickel

Product Description

The DELTANA DSB55B15A is a 5-inch by 5-inch square ball bearing hinge finished in Antique Nickel. Ball bearing construction reduces friction and supports smooth, consistent door swing under repeated use. The square corner profile suits traditional and transitional door frames in both residential and light commercial settings. This hinge is sold as a pair and is intended for installation by finish carpenters, general contractors, or experienced door hardware installers working on interior or exterior door applications requiring a durable, full-size hinge.

The DSB55B15A is suited for use on heavy interior doors, entry doors, and passage doors where a larger 5-inch by 5-inch hinge is specified. The Antique Nickel finish integrates with a range of hardware finishes common in traditional, transitional, and contemporary architectural settings. Typical applications include residential entry doors, commercial office doors, and institutional interior doors where smooth operation and finish consistency are priorities.

Compatibility

Installation Notes

Installation is typically performed by a licensed finish carpenter or door hardware installer. Power down any electric strike or access control hardware associated with the door before beginning work. Use a sharp chisel and router for accurate mortise preparation to ensure flush leaf seating. Follow applicable building codes for fire-rated door assemblies, as hinge specifications on rated doors must match the door and frame listing.
