Using the Deltana 4' x 4' x 5/8' Radius Hinge with Ball Tips is easy. First, make sure the door and the frame are clean and dry. Then, align the hinge with the door and frame and use the #10 x 1' wood screws provided to attach it. Make sure the screws are tightened properly. As for maintenance, regularly wipe the hinge with a soft, dry cloth to keep it clean. Avoid using abrasive cleaners as they might damage the finish. Also, if you notice any looseness, check the screws and tighten them if necessary. This will ensure your hinge keeps working smoothly and looking great for a long time.
