Deltana S45BBU26 Square Hinge Heavy Duty Ball Bearing

Product Description

The DELTANA S45BBU26 is a heavy-duty square hinge designed for commercial and residential door applications where durability and smooth operation are required. Measuring 4.5 inches by 4.5 inches, it features a ball bearing construction that reduces friction and supports high-cycle use. The Bright Chrome finish provides a clean, polished look suited to both interior and exterior door installations. Sold as a pair, this hinge is specified by carpenters, millwork contractors, and general contractors working on medium-to-heavy door assemblies that demand reliable, long-term performance.

This hinge is appropriate for residential and light commercial door installations where a square-corner profile is required. It is commonly installed on interior passage doors, entry doors, and commercial doors in offices, hospitality, and institutional settings. The ball bearing design makes it well suited for high-traffic doors that cycle frequently. Each sales unit ships as a pair, allowing a complete single-door installation with one order quantity when used alongside a standard three-hinge door prep.

Installation Notes

Installation is performed by finish carpenters, door hardware installers, or general contractors using standard woodworking chisels, a hinge template, and a power drill. Power should not be required for this mechanical hardware, but any electric strike or access control wiring at the door should be de-energized before work begins. Verify door weight and frequency of use against the hinge duty rating before installation. Follow the door manufacturer's hinge placement specifications and applicable building codes for fire-rated door assemblies.
