Deltana DSH4R43 Radius Spring Hinge 4x4 Bright Brass

Product Description

The DELTANA DSH4R43 is a 4-inch by 4-inch radius corner spring hinge finished in Bright Brass. Spring hinges are self-closing hardware used in door assemblies where code compliance or operational convenience requires the door to return to a closed position automatically. This hinge is constructed from solid brass and ships as a single unit. It measures 5.25 inches in length, 2.8 inches in width, and 0.9 inches in height and weighs 0.8 pounds. The DSH4R43 is installed by licensed carpenters, millwork contractors, or door hardware specialists on commercial and residential door applications.

This spring hinge is suited for interior and light-duty door installations where a self-closing function is required. The Bright Brass finish makes it appropriate for decorative door hardware applications in residential entryways, interior passage doors, and light commercial settings. The radius corner profile fits standard door preparations that call for a radius corner mortise rather than a square corner cut. Installation is sold per each unit.

Installation Notes

Spring hinges are typically installed by carpenters or door hardware professionals using a chisel and drill to prepare the mortise pocket on both the door and the frame. Power down or disengage any electronic access control hardware before working on the door. Follow applicable local building codes, including IBC and ADA requirements where self-closing doors are mandated. Do not over-tension the spring adjustment beyond the manufacturer-recommended setting, as this can cause premature wear on the spring mechanism.
