Deltana SS45NBU32D Square Hinge 4.5x4.5 Satin Stainless

Product Description

The DELTANA SS45NBU32D is a 4.5 inches x 4.5 inches square architectural door hinge finished in satin stainless steel. Built from stainless steel, this hinge is suited for interior and exterior door applications where corrosion resistance and a clean, modern profile are required. The non-removable pin (NRP) design indicated by the NBU designation adds a layer of security by preventing pin removal when the door is in the open position. Carpenters, finish contractors, and door hardware installers work with this hinge on commercial and residential projects where a consistent satin stainless appearance is specified.

The SS45NBU32D fits standard door installations requiring a 4.5 inches x 4.5 inches square-corner hinge. The satin stainless steel finish coordinates with contemporary door hardware and suits high-traffic environments where durability matters. It is sold as a pair, making it straightforward to order the correct quantity for single-door applications or to calculate quantities for multi-door projects.
