Deltana S35R5BB4 Ball Bearing Radius Hinge Satin Brass

Product Description

The DELTANA S35R5BB4 is a ball bearing radius corner hinge designed for interior and exterior door installations where smooth, long-term operation is required. Measuring 3.5 inches by 3.5 inches with a 0.625-inch throw, this hinge features a radius corner profile and is finished in satin brass. Ball bearing construction reduces friction during door swing, extending service life compared to plain bearing alternatives. The solid construction and satin brass finish make it suitable for both functional and finish-visible applications in residential and light commercial settings. Sold per pair, this hinge is installed by carpenters, finish trades, and door hardware professionals.

The S35R5BB4 is used in standard door frame installations where a 3.5 x 3.5 inch hinge is specified. The radius corner profile fits routed hinge mortises designed for radius-corner leaves, which is the most common profile in residential and light commercial door prep. The satin brass finish coordinates with complementary architectural hardware in brass or gold-tone families. Each order unit is one pair of hinges, making it straightforward to specify per door leaf.

Installation Notes

Installation is performed by qualified carpenters or door hardware tradespeople using standard chiseling or router mortising techniques to prepare the door edge and frame. Verify that the existing or new mortise is cut for a radius corner leaf profile before installation. Secure all fasteners fully and check door swing alignment before final close-out. Follow applicable local building codes for fire-rated door assemblies, as rated doors may require listed hardware.
