Deltana S45BBUSPW Square Hinge 4.5x4.5 in Heavy Duty White

Product Description

The DELTANA S45BBUSPW is a heavy-duty, ball-bearing square hinge finished in white, designed for commercial and residential door applications where smooth operation and long-term durability are required. Measuring 4.5 inches x 4.5 inches, this hinge is built to handle high-frequency door cycles without wear degradation. The ball-bearing construction reduces friction at the pivot point, supporting heavier door slabs and maintaining consistent swing alignment over time. Sold as a pair, it is a standard specification item for interior and exterior door installations requiring a clean, square-corner profile.

This hinge suits residential and light commercial door framing projects where a square-corner hinge profile is specified. It is appropriate for wood or hollow-metal door frames and is commonly installed on entry doors, interior passage doors, and utility doors where load-bearing capacity and finish consistency are priorities. The white finish coordinates with painted door and frame assemblies. Each order unit is one pair.

Installation Notes

Installation is typically performed by a finish carpenter, door hardware installer, or general contractor. The door slab and frame must be fully mortised to the hinge leaf dimensions before fastening. All door weight should be relieved and the door secured before removing existing hinges during a replacement installation. Follow applicable building codes for door hardware specifications in commercial applications.
