Deltana S45BBU3 Heavy Duty Ball Bearing Hinge 4.5x4.5 Brass

Product Description

The DELTANA S45BBU3 is a heavy-duty square door hinge built with ball bearings for smooth, consistent swing performance on high-traffic door applications. Measuring 4.5 inches by 4.5 inches, this hinge is sized for substantial commercial and residential doors where a standard-weight hinge would be undersized. The bright brass finish provides a clean, polished appearance suited to architectural door hardware installations. Ball bearing construction reduces friction and wear over the service life of the hinge. Sold as a pair, the S45BBU3 is a common choice for door installations requiring both durability and a refined finish.

This hinge is appropriate for interior and exterior door installations where heavy-duty swing hardware is specified. Typical applications include solid-core wood doors, heavy panel doors, and commercial entry doors in both residential and light commercial construction. The 4.5-inch square pattern fits standard mortise hinge preps on door edges and frames. Finish carpenters, door and hardware installers, and commercial contractors are the primary trades specifying this hinge.

Installation Notes

Installation is performed by finish carpenters or door hardware installers following standard mortise hinge prep procedures.

Follow applicable building code requirements for hinge quantity and placement based on door height, width, and weight.
