Deltana S45BBU10B Heavy Duty Ball Bearing Hinge 4.5in

Product Description

The DELTANA S45BBU10B is a heavy-duty square door hinge built for high-traffic and demanding applications where standard hinges fall short. Measuring 4.5 inches x 4.5 inches, this hinge features a ball-bearing construction that reduces friction and supports smooth, consistent door operation over years of use. It is finished in oil rubbed bronze, providing a dark, matte appearance that suits traditional and transitional architectural styles. Sold as a pair, this hinge is suited for installation by carpenters, finish contractors, and commercial door hardware professionals working on both new construction and replacement projects.

The S45BBU10B is appropriate for residential and light commercial interior and exterior door applications where a heavy-duty hinge is required. Its square corner profile matches standard mortise preparations found on most pre-hung and custom door frames. The 4.5-inch leaf size accommodates heavier door assemblies such as solid-core wood doors and metal-clad units where additional hinge mass and bearing support are necessary for long-term performance.

Key Features

• 4.5 inches x 4.5 inches square leaf provides a full mortise footprint for solid-core and heavy doors
• Ball-bearing construction reduces pivot friction and extends service life under frequent use
• Oil rubbed bronze finish suits traditional and transitional interior and exterior applications
• Sold as a pair, matching standard door hardware ordering practices
• Heavy-duty rated construction supports heavier door assemblies where standard hinges are insufficient

Compatibility

Designed as an OEM-style replacement or new-installation hinge for standard full-mortise door preparations requiring a 4.5-inch square hinge profile.

Installation Notes

Installation is performed by a licensed carpenter or door hardware professional using standard mortise chisels and a drill. Power to any electric hardware integrated into the door frame should be disconnected before beginning work. Ensure the mortise pocket depth matches the hinge leaf thickness to produce a flush-mounted result. Follow applicable building code requirements for hinge quantity and placement on fire-rated door assemblies.
