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.
