Deltana DSB43-UNL Square Door Hinge Unlacquered Bright Brass

Product Description

The DELTANA DSB43-UNL is a 4-inch x 4-inch square door hinge finished in unlacquered bright brass. Solid brass construction gives it lasting durability and a clean, traditional profile suited for interior and exterior door installations. The unlacquered finish allows the brass to develop a natural patina over time, making it a common choice on high-end residential and light commercial door hardware projects. Sold as a pair, this hinge is sized for standard full-mortise door applications and is installed by carpenters, finish contractors, and door hardware specialists.

This hinge is used on residential and light commercial swinging doors where a square-corner, full-mortise hinge is specified. The 4-inch x 4-inch leaf size suits standard interior passage doors and many exterior door applications. The unlacquered bright brass finish coordinates with matching DELTANA architectural hardware in brass. Each order ships as one pair.

Power down any associated electronic hardware such as electric strikes or access control devices before beginning work. Fasten with screws appropriate to the door and frame material — do not overdrive fasteners into solid brass leaves. Follow applicable building codes for hinge quantity and placement based on door height and weight.
