Sring hinges are available in a variety of sizes, finishes and styles. They ensure the safe and efficient operation of your doors, and are available in single or double acting. The hinges allow the opening of the door in either direction and automatically return in its closed position. Manufactured in the United States of selected quality materials, hinges provide a silent and reversible action for institutional, residential, commercial and industrial applications where self-closing doors are required. The jamb leaf is surface applied to the jamb; no hanging strip is required, and their spring tension is adjustable. Hinges are supplied with all screws needed for installation.
