Deltana S35R4BB1B Ball Bearing Door Hinge 3.5x3.5 Paint Black

Product Description

The DELTANA S35R4BB1B is a 3.5 x 3.5 inch radius corner door hinge with a ball bearing design and a paint black finish. Constructed for consistent, smooth operation, the ball bearing mechanism reduces friction and wear over repeated use. The radius corner profile provides a clean, traditional look suited to both interior and exterior door installations. Sold as a pair, this hinge is appropriate for residential and light commercial applications where a durable, finished hardware component is required. Licensed carpenters, finish carpenters, and door hardware installers are the primary trade professionals who spec and install this hinge.

This hinge is intended for use on standard swing doors in residential and light commercial settings. The 3.5 x 3.5 inch leaf size fits common interior and exterior door frame preparations. The paint black finish integrates with dark hardware schemes and painted door and frame systems. Each sales unit is one pair, making it straightforward to order per door opening.

Designed as an OEM-style replacement or new-installation hinge for standard residential and light commercial swing door applications requiring a 3.5 x 3.5 inch radius corner hinge mortise.

Installation Notes

Installation is performed by finish carpenters or door hardware installers using standard mortise chisels and a screw gun. Power to any electric strike or access control hardware associated with the door should be disconnected before removing or replacing hinges. Follow the door and frame manufacturer's mortise depth specifications to ensure proper leaf seating and door alignment. Do not overtighten hinge screws, as this can strip the mortise or distort the hinge leaf.
