Deltana DSB4B19 Square Hinge Ball Bearings Flat Black

Product Description

The DELTANA DSB4B19 is a 4-inch by 4-inch square door hinge with ball bearings, designed for smooth, long-lasting operation on residential and light commercial doors. The flat black finish provides a clean, consistent appearance suitable for modern and transitional door applications. Ball-bearing construction reduces friction at the pivot point, making this hinge appropriate for heavier door panels where a standard butt hinge would wear prematurely. Licensed carpenters, door hardware installers, and finish contractors are the typical trades specifying this product. Sold as a pair, this hinge is built to OEM architectural hardware standards and is suited for high-cycle door installations.

This hinge is used on interior and exterior hinged doors in residential construction and light commercial settings. It is appropriate for full-mortise installation on wood door frames and door slabs where a square-corner hinge profile is required. The flat black finish coordinates with modern door hardware collections. The DSB4B19 is sold by the pair, making it straightforward to order for single-door applications or to calculate quantities for multi-door projects.

Installation Notes

Installation is performed by finish carpenters or door hardware installers using standard mortise chisels and a drill. Power down any electric strike or access control hardware associated with the door before beginning work. Follow applicable local building codes for door hardware installation. Do not force the hinge leaves into an undersized mortise, as this can stress the hinge knuckle and affect bearing alignment.
