Deltana DSB310B Square Door Hinge 3x3 in Oil Rubbed Bronze

Product Description

The DELTANA DSB310B is a 3-inch x 3-inch square door hinge finished in oil rubbed bronze. Built for architectural door hardware applications, this hinge is sold as a pair and is designed for installation on interior or exterior doors where a traditional square-corner profile is required. The oil rubbed bronze finish provides a dark, hand-applied look suited to period and transitional door styles. At 0.8 pounds per pair, the DSB310B is a solid, production-grade hinge appropriate for residential and light commercial door installations completed by carpenters, finish contractors, and general tradespeople.

This hinge is appropriate for standard door applications in residential construction and renovation projects. The square corner design fits mortise cutouts on both door and frame without the need for corner chiseling, making it a common choice in new construction and replacement scenarios where square-corner prep already exists. Sold in pairs, it suits standard door hang configurations requiring matched hinge sets.

Installation Notes

Installation is typically performed by a finish carpenter or general contractor using a chisel, mortise template, and screw driver or drill with appropriate bit. Power must be off to any electrified hardware in the door or frame before beginning work. Verify that the door frame mortise dimensions match the 3-inch x 3-inch hinge leaf before fastening. Follow applicable local building codes for door hardware installation in fire-rated or egress door assemblies.
