Deltana DSB353-UNL-R Square Hinge 3.5x3.5 Unlacquered Brass

Product Description

The DELTANA DSB353-UNL-R is a 3.5 x 3.5 inch square residential door hinge finished in unlacquered bright brass. Designed for interior and exterior door applications, this hinge provides a clean, square-corner profile suited to traditional and transitional door framing. The unlacquered finish allows the natural brass to develop a living patina over time, which is a common specification in restoration and custom millwork projects. Sold as a pair, it installs directly onto standard door prep and is appropriate for light-duty residential swing doors. Carpenters, finish contractors, and door hardware installers work with this type of hinge daily.

This hinge is intended for residential door installations where a square-corner profile and solid brass construction are specified. Typical applications include interior passage doors, closet doors, and entry doors in residential new construction or remodel projects. The unlacquered bright brass finish is often selected for historic restoration work or when a warm, evolving metal tone is desired. The pair configuration covers a single hinge location and is ordered in multiples to meet the full hinge count required per door per local building practice.

Installation Notes

Installation is performed by carpenters or finish hardware contractors as part of door hanging or hardware replacement work. Power down any electric strike or access control hardware associated with the door before beginning work. Use a sharp chisel to mortise the hinge leaf flush with the door edge and frame jamb to ensure proper door swing and gap uniformity. Follow door manufacturer specifications and local building code requirements for hinge count and placement height.
