Deltana S45BBU5 Square Hinge Heavy Duty Ball Bearing

Product Description

The DELTANA S45BBU5 is a heavy-duty square door hinge finished in antique brass, designed for commercial and residential door installations where durability and smooth operation are required. Built with ball bearings, the hinge reduces friction on high-traffic doors and maintains consistent swing performance over time. At 4.5 inches by 4.5 inches, this hinge is sized for substantial door applications. It is sold as a pair and is suited for installation by door hardware specialists, commercial finish carpenters, and general contractors working on architectural millwork projects.

This hinge is appropriate for heavy interior and exterior doors in both residential and light commercial settings. The antique brass finish suits traditional and transitional architectural styles. The heavy-duty construction makes it a practical choice for solid-core wood doors and other demanding door assemblies where a standard-weight hinge would be undersized. Each order yields one pair of hinges.

Installation Notes

Installation is typically performed by a finish carpenter, door hardware installer, or licensed contractor. The door and frame must be mortised to the correct hinge leaf depth before fastening. Ensure the door is properly supported and the opening is plumb and square prior to installation. Follow applicable local building codes for door hardware requirements on egress and fire-rated assemblies.
