Deltana DSB4R419-RZ 4x4 Radius Door Hinge Black

Product Description

The DELTANA DSB4R419-RZ is a 4 inch x 4 inch radius corner door hinge with a 1/4 inch radius and a black finish. Built for architectural hardware applications, this hinge is sold as a pair and is suited for interior and exterior door installations where a clean, traditional radius corner profile is required. The black finish provides a uniform, durable appearance consistent with standard architectural hardware programs. Licensed contractors, carpenters, and door hardware installers will find this hinge appropriate for both new construction and replacement work on residential and light commercial doors.

This hinge is used in door frame and door slab installations where a radius corner mortise hinge is specified. The black finish coordinates with door hardware finish packages in residential and commercial settings. Sold per pair, it is appropriate for use on standard door applications where a 4 inch x 4 inch hinge leaf size is called out by the project spec or original equipment requirement.
