Using your Deltana 3 - 1/2 x 3 - 1/2 square hinge is easy. First, make sure the door and the frame are clean and dry. Align the hinge with the pre - drilled holes on the door and frame, then use the #10 x 1 wood screws to secure it in place. When opening and closing the door, do it gently to avoid putting too much stress on the hinge. For maintenance, wipe the hinge regularly with a soft, dry cloth to keep it looking shiny. If you notice any dirt or grime, you can use a mild soap and water solution, but make sure to dry it thoroughly afterwards. Avoid using abrasive cleaners as they can damage the finish. With proper care, this hinge will serve you well for a long time.
