Deltana DSB35B19 Square Door Hinge Ball Bearing Black

Product Description

The DELTANA DSB35B19 is a 3.5-inch by 3.5-inch square door hinge with ball bearings, finished in black. It is designed for interior and exterior door installations where a clean, square-corner profile is required. The ball bearing construction reduces friction and supports smooth, consistent door swing over repeated cycles. Sold as a pair, this hinge is suited for residential and light commercial door applications. Licensed carpenters, door and hardware installers, and general contractors typically specify this hinge where architectural hardware standards require a durable, finished product.

The DSB35B19 fits standard door applications requiring a 3.5-inch square hinge. The black finish makes it appropriate for modern, transitional, and industrial interior design schemes. It is commonly installed on interior passage doors, closet doors, and utility room doors in residential construction and light commercial remodeling projects. Each pair provides two matching hinges for a single door leaf installation.

Installation Notes

Installation is typically performed by a licensed carpenter or door hardware installer using a chisel, router, or hinge template to mortise the door edge and jamb. Power down any electric strike or access control hardware before servicing the door frame. Follow local building codes for door hardware requirements in commercial occupancies. Do not overtighten fasteners into the hinge leaf, as this can cause door binding or misalignment.
