Deltana DSB45B15A Square Hinge Ball Bearing Antique Nickel

Product Description

The DELTANA DSB45B15A is a 4.5-inch x 4.5-inch square door hinge with ball bearings, finished in antique nickel. Built for architectural and door hardware applications, it is designed to provide smooth, low-friction pivot action over repeated use cycles. The ball bearing construction reduces wear on the knuckle under heavy door loads. The antique nickel finish suits interior and exterior door installations where a classic, muted metallic appearance is specified. This hinge is sold as a pair and is appropriate for installation by carpenters, finish contractors, and general trades working on commercial or residential door assemblies.

This hinge fits standard door and frame applications requiring a full-mortise square-corner hinge. The 4.5-inch leaf size is commonly specified for heavy interior doors, entry doors, and commercial passage doors where additional bearing surface and load capacity are required. The antique nickel finish integrates with period-style and transitional architectural hardware programs. Installation is typically performed during door pre-hanging or finish carpentry, and the pair format supports standard per-door hinge sets when combined with additional pairs as required by door weight and height specifications.

Installation Notes

Installation is performed by finish carpenters or licensed contractors using standard mortise chisels, a drill, and a hinge template. Power down any access control or electric strike hardware associated with the door assembly before beginning work. Verify door weight and door height against applicable building code requirements to confirm the correct number of hinges per door. Do not over-drive fasteners into the hinge leaf, as this can distort the knuckle alignment and affect swing performance.
