Deltana S44R5BB4 Ball Bearing Radius Hinge Satin Brass

Product Description

The DELTANA S44R5BB4 is a 4-inch by 4-inch radius corner door hinge with ball bearings, finished in satin brass. It is constructed for use in architectural and door hardware applications where smooth, reliable pivot action is required. The radius corner profile and satin brass finish make it suitable for interior and exterior door installations in both residential and light commercial settings. The ball bearing design reduces friction and wear over the hinge's service life. This hinge is sold as a pair and is typically installed by carpenters, finish contractors, or general tradespeople during door hardware fit-out.

This hinge is suited for standard door installations requiring a 4-inch by 4-inch full-mortise hinge with a 5/8-inch radius corner. The satin brass finish integrates with a wide range of door and frame hardware. Sold in pairs, it is appropriate for interior passage doors, entry doors, and similar applications where a ball bearing hinge is specified. The architectural-grade construction makes it a common choice on projects where hardware finish consistency and long service life are priorities.
