Deltana S44R5BB3 Radius Corner Door Hinge Ball Bearing Bright Brass

Product Description

The DELTANA S44R5BB3 is a full-mortise door hinge with radius corners and integrated ball bearings, sold as a pair. Built for architectural and commercial door applications, this hinge measures 4 inches by 4 inches with a 5/8-inch radius corner profile and ships in a bright brass finish. The ball bearing construction reduces friction at the pivot point, supporting smooth, consistent door operation under repeated use. Licensed contractors and finish carpenters typically specify this hinge for interior and exterior door installations where a clean, traditional radius-corner profile is required alongside durable bearing performance.

This hinge is suited for residential and light commercial door installations where a mortise-style hinge is the correct application. The bright brass finish coordinates with standard architectural hardware in brass or gold-tone families. Packaged and sold as a pair, it fits standard door frame preparations calling for a 4 inches by 4 inches hinge cutout. The radius corner geometry matches routed or pre-cut mortise pockets with a 5/8-inch radius profile.

Key Features

• Ball bearing pivot for reduced friction and long service life
• Radius corner profile at 5/8 inches for standard mortise compatibility
• 4 inches x 4 inches leaf dimensions suit residential and light commercial doors
• Bright brass finish for a traditional architectural appearance
• Sold as a pair to cover a single door hinge position

Compatibility

Designed as an OEM-style replacement or new-install hinge for standard full-mortise door preparations requiring a 4 inches by 4 inches radius-corner hinge with ball bearings.

Installation Notes

Installation is typically performed by a finish carpenter, door installer, or licensed contractor. Ensure the door and frame mortise pockets are routed cleanly to the correct depth before mounting. All fasteners should be driven with the door held plumb and square to avoid binding. Verify hinge leaf seating is flush with the door and frame face before final fastener torque.
