Deltana DSH4R426 Spring Hinge 4x4 Radius Bright Chrome

Product Description

The DELTANA DSH4R426 is a 4-inch x 4-inch radius-corner spring hinge finished in Bright Chrome. Spring hinges are self-closing door hardware components that use an internal spring mechanism to automatically return a door to the closed position after each use. This hinge is designed for interior door installations where building codes or facility requirements mandate self-closing function. Licensed carpenters, door hardware installers, and general contractors typically handle installation in both residential and light commercial settings.

The DSH4R426 suits interior door applications where automatic door closure is required, such as fire-rated corridor doors, utility room entries, and access doors in commercial or multifamily residential construction. The Bright Chrome finish coordinates with contemporary and traditional door hardware sets. The radius corner geometry is compatible with standard mortised door and frame preparations that call for rounded hinge corners rather than square-cut profiles.

Compatibility

Designed as an OEM-style replacement or new-installation spring hinge for standard interior doors requiring a 4-inch x 4-inch radius-corner hinge mortise preparation.

Installation Notes

Spring hinge installation is typically performed by a licensed carpenter or door hardware installer using a chisel, hinge template, and standard hand tools. Ensure the door is properly supported and the spring tension is adjusted only with the appropriate spring adjustment pin included or supplied with the hinge set. Follow all applicable local building codes, including IBC self-closing door requirements where fire-rated assemblies are involved. Do not over-tension the spring, as excessive force can damage the door frame or interfere with door latch engagement.
