Deltana DSH4R52D Spring Hinge 4x4 in Zinc Dichromate

Product Description

The DELTANA DSH4R52D is a 4-inch x 4-inch spring hinge with a 5/8-inch corner radius, finished in zinc dichromate plating. Spring hinges are self-closing door hardware components that use an internal coil mechanism to return a door to the closed position after each use. This hinge is sized for standard interior and light commercial doors and is installed by carpenters, finish contractors, and door hardware specialists. The zinc dichromate finish provides corrosion resistance suitable for dry interior environments. The unit ships individually and weighs 0.8 pounds.

This hinge is suited for residential and light commercial applications where a self-closing door function is required without the bulk of a hydraulic door closer. Typical installations include utility rooms, stairwell doors, and interior fire-rated door assemblies where self-closing hardware is specified by code. The 4-inch x 4-inch leaf size accommodates standard interior door thicknesses and frame widths common in residential and light commercial construction.

Installation Notes

Spring hinges are installed by carpenters or finish hardware contractors using standard door hinge installation techniques. Power down any adjacent electric strike or access control hardware before working on the door frame. Mortise the hinge leaf flush into the door edge and frame jamb to ensure proper door alignment and consistent spring tension. Follow applicable local building codes and fire-door assembly listings when installing self-closing hardware on rated assemblies.
