Deltana DSB353-UNL Square Door Hinge Unlacquered Bright Brass

Product Description

The DELTANA DSB353-UNL is a 3.5 x 3.5 inch square door hinge finished in unlacquered bright brass. Sold as a pair, it is designed for interior and exterior door installations where a clean, square-corner profile is required. The unlacquered finish exposes the natural brass tone and will develop a patina over time, making it a common choice for period-style or high-end residential woodwork. Installation is handled by carpenters, finish trim contractors, and door hardware specialists working on new construction or renovation projects.

This hinge is suited for standard residential and light commercial door applications. The 3.5 x 3.5 inch leaf size is a common fit for interior passage doors and lighter exterior doors. The square corner design is appropriate for doors routed with square mortise pockets. Contractors specifying solid brass hardware for consistent finish appearance across a project will find this hinge compatible with that approach.

Installation Notes

Installation is performed by carpenters or door hardware technicians using standard chisels, drill bits, and screwdrivers. Mortise the door edge and jamb to the correct leaf depth before mounting to ensure flush seating. Verify door weight and frequency of use are within the load rating of the hinge before installation. Follow applicable building codes for door hardware in the jurisdiction of the project.
