Using these Deltana hinges is easy. First, choose the right location on your door and frame. Mark the spots and use the #10 x 1 - inch wood screws to attach the hinges firmly. For Zig - Zag installations, follow the specific layout requirements. When it comes to maintenance, clean the hinges regularly with a soft, dry cloth to keep them looking good. Avoid using harsh chemicals as they can damage the finish. If you notice any loose screws, tighten them promptly to ensure the hinges work properly and last a long time.
