Deltana DSB35B4 Square Hinge Ball Bearing Satin Brass

Product Description

The DELTANA DSB35B4 is a 3.5 x 3.5 inch square door hinge with ball bearings, manufactured from solid brass with a satin brass finish. Ball bearing construction reduces friction and wear on high-cycle doors, making this hinge well suited for commercial and residential applications where smooth, quiet operation is required. Sold as a pair, each hinge measures 3.5 inches in leaf length and 3.5 inches in leaf width. The satin brass finish provides a consistent, low-sheen appearance that holds up in interior door installations. This is a product for door hardware installers and finish carpenters working on architectural millwork and door framing projects.

The DSB35B4 is appropriate for interior and light-duty exterior door installations in residential and light commercial settings. It is used on passage doors, entry doors, and architectural doors where a square-corner hinge profile is specified. The satin brass finish is a common specification in hospitality, office, and residential renovation work where warm-toned hardware finishes are called out. Installers working from an architectural hardware schedule will find this hinge fits standard door and frame prep for 3.5 inch square hinge cutouts.

Installation Notes

Installation is performed by door hardware installers or finish carpenters using a chisel or router to prepare the mortise on both the door edge and door frame. Power down any access control or electric strike hardware associated with the door before service. Verify hinge leaf dimensions match the existing mortise cutout before installation to avoid frame or door edge rework. Follow applicable building codes for hinge count and placement based on door height and weight.
