Deltana DSH4R41B Radius Spring Hinge 4x4 Flat Black

Product Description

The DELTANA DSH4R41B is a radius corner spring hinge designed to provide self-closing action on interior and exterior doors. The spring mechanism automatically returns the door to a closed position after each use, making it a standard choice for fire-rated door assemblies and high-traffic doorways that require controlled closure. Finished in flat black, this hinge suits modern and industrial architectural styles. Measuring 4 inches by 4 inches with a 1/4-inch radius corner, it fits standard residential and light commercial door preparations. Licensed door and hardware installers and finish carpenters are the primary tradespeople who specify and install this component.

The DSH4R41B is suited for residential and light commercial applications where a self-closing door function is required. Common install scenarios include entry doors, corridor doors, utility room doors, and any passage that must remain closed between uses for code compliance, fire separation, or general building management. The flat black finish integrates cleanly with contemporary door hardware sets.

Installation Notes

Installation is typically performed by a finish carpenter, door installer, or general contractor. Before installation, ensure the door and frame are unpainted in the hinge mortise area and that the existing hinge prep matches the 4-inch leaf size. Spring tension on self-closing hinges should be adjusted only with the door secured open using an appropriate door holder or wedge to prevent uncontrolled closing during work. Refer to local building codes and NFPA 80 requirements when installing on fire-rated door assemblies.
