Using the Deltana Radius Hinge with Ball Tips is easy. First, choose the right location on your door and the door frame. Then, use the #9 x 3/4' wood screws to attach the hinge securely. Make sure the corners with the 5/8' radius are properly aligned. For maintenance, you can use a soft cloth to wipe off dust regularly. If it gets dirty, use a mild soap and water solution, then dry it thoroughly. Avoid using abrasive cleaners as they can damage the finish. When installing, ensure the hinge is suitable for your door's weight as it comes in a heavy - duty option. If you're not sure, consult a professional.
