Deltana DSB453-UNL Square Hinge 4.5x4.5 Unlacquered Brass

Product Description

The DELTANA DSB453-UNL is a 4.5-inch x 4.5-inch square door hinge finished in unlacquered bright brass. Solid construction and a full-square leaf design make this hinge suited for interior and exterior doors in commercial and residential applications. The unlacquered finish preserves the natural brass appearance and allows the metal to develop a natural patina over time. Carpenters, finish contractors, and door hardware installers specify this hinge where a clean, square corner profile is required. Sold as a pair, it is appropriate for medium to heavy door applications where a larger hinge footprint provides added stability and load distribution.

The DSB453-UNL is used in door installations requiring a full-square hinge with a bright brass aesthetic. Typical applications include entry doors, interior passage doors, and commercial-grade door frames where appearance and durability are both priorities. The unlacquered bright brass finish is well suited to traditional and transitional architectural styles. This hinge is sold per pair, making it straightforward to specify by door for new construction and renovation projects alike.

Installation Notes

Installation is performed by carpenters or door hardware installers using standard chiseling and mortising techniques to seat the hinge leaf flush with the door edge and frame. Power down any access-control or electric-strike hardware associated with the door before beginning work. Follow local building codes and manufacturer door prep specifications for hinge placement and fastener requirements. Avoid over-driving screws, which can strip the mortise and affect hinge alignment.
