Deltana DSH4R5TT2D Spring Hinge 4x4 in Zinc Dichromate

Product Description

The DELTANA DSH4R5TT2D is a 4-inch x 4-inch spring hinge with a 5/8-inch radius corner on one leaf and a square corner on the other, finished in zinc dichromate plating. Spring hinges are self-closing door hardware designed to return a door to a closed position without a separate closer mechanism. This hinge is built for interior door applications where code-compliant self-closing function is required, such as fire-rated corridor doors or utility room entries. It measures 5.25 inches in length, 2.8 inches in width, and 0.9 inches in height, and weighs approximately 0.8 pounds per unit.

This spring hinge is suited for residential and light commercial door installations where a self-closing hinge is needed to meet fire code or building code requirements. The mixed corner profile — radius on one leaf, square on the other — accommodates door frames and slabs that use different corner styles, providing installation flexibility. It is sold as a single unit and is appropriate for standard interior door applications handled by carpenters, door hardware installers, or general contractors.

Installation Notes

Spring hinges are installed by carpenters or door hardware professionals and require standard hinge mortising tools. The spring tension is adjustable after installation using the provided tension pin — follow the manufacturer's instructions and do not over-tension the spring. Ensure the door and frame are properly aligned before setting final spring tension. Check local building and fire codes for self-closing door requirements before installation.
