Deltana DSB45B19 Square Hinge Ball Bearing Black

Product Description

The DELTANA DSB45B19 is a 4.5 inch x 4.5 inch square door hinge with ball bearings, sold as a pair and finished in black. Ball bearing construction reduces friction during door operation and supports consistent, smooth swing over the service life of the hinge. This hardware is suited for interior and exterior door installations in residential and light commercial applications. Licensed contractors and finish carpenters install this type of hinge during new construction and renovation work where a square-corner profile and a matte black finish are specified. The hinge weighs approximately 2.1 pounds per pair and ships as a single pair unit.

This hinge is designed for standard door applications where a full-mortise, square-corner hinge with ball bearings is required. It fits doors where the leaf size calls for a 4.5 inch x 4.5 inch footprint. Typical installations include interior passage doors, entry doors, and utility doors in both residential and light commercial settings. The black finish coordinates with contemporary and transitional hardware styles and is appropriate for use with black door levers, knobs, and other architectural hardware in the same finish family.

Installation Notes

Installation is typically performed by a finish carpenter, general contractor, or licensed door hardware installer. Mortise the hinge leaf flush into both the door edge and the door frame jamb before fastening. Ensure the door is properly shimmed and aligned before final screw seating to prevent binding. Follow applicable local building codes for door hardware installation in fire-rated or exterior door assemblies.
