Deltana DSH4R42D Radius Spring Hinge Zinc Dichromate

Product Description

The DELTANA DSH4R42D is a radius-corner spring hinge designed for standard door installations where self-closing action is required. Measuring 4 inches x 4 inches with a 0.25-inch radius corner, this hinge provides consistent tension return to keep doors closed without a separate door closer. The zinc dichromate plated finish offers corrosion resistance suitable for interior applications. Carpenters, door installers, and general contractors install this hardware as part of new door assemblies or retrofit projects where code or facility requirements call for self-closing doors.

The DSH4R42D is suited for residential and light commercial door applications where a self-closing hinge replaces a standard butt hinge in the same mortise location. The radius corner profile matches common door prep dimensions, making it a direct drop-in for most pre-mortised door frames. It is sold as a single unit, allowing installers to specify the exact quantity needed per door leaf.

Installation Notes

Installation is performed by carpenters or door hardware installers using a chisel, router, or pre-mortised door prep. Ensure the door is properly supported and the frame is plumb and square before mounting. Spring tension adjustment is typically made with the tension pin or adjustment tool included or specified by the manufacturer — do not over-tension the spring coil. Verify local building codes, including accessibility requirements (ADA or IBC), for self-closing door hardware specifications before installation.
