Deltana S44R5BB10B Radius Hinge Ball Bearings Oil Rubbed Bronze

Product Description

The DELTANA S44R5BB10B is a 4 x 4 x 5/8 inch radius corner door hinge with ball bearings, finished in oil rubbed bronze. Designed for interior and exterior door applications, this hinge provides smooth, consistent pivot action supported by ball bearing knuckles that reduce friction and wear over repeated cycles. The radius corner profile follows the most common door frame mortise geometry found in residential and light commercial construction. Architectural hardware professionals, carpenters, and finish contractors specify this hinge where a dark, oil rubbed bronze finish is required to match period-style or transitional hardware sets. Sold as a pair.

This hinge is suited for standard passage doors in residential homes and light commercial buildings where a mortised ball bearing hinge is specified. The oil rubbed bronze finish coordinates with matching lever sets, flush bolts, and other architectural hardware in the same finish family. The 4 x 4 inch leaf size is appropriate for doors up to standard residential weight and thickness. The 5/8 inch radius corner profile fits routed mortises prepared to the same radius, which is the most widely used corner cut in pre-hung door manufacturing and field installation.

Compatibility

Designed as an OEM-style replacement or new-installation hinge for standard mortised residential and light commercial doors requiring a 4 x 4 inch radius corner ball bearing hinge in an oil rubbed bronze finish.

Installation Notes

Installation is typically performed by a finish carpenter or licensed contractor using a chisel or router to prepare the mortise to the correct depth and radius corner profile. Remove the door from the frame and ensure the existing or new mortise matches the 5/8 inch radius corner before fastening. Use the manufacturer-supplied or appropriately sized screws for the door and frame material. Follow all applicable local building codes for door hardware when used in fire-rated or egress assemblies.
