Using these Deltana hinges is easy. Just line them up with the door and the door frame, then use the #9 x 1' wood screws to attach them. Make sure the screws are tightened properly for a secure fit. When using the door, don't apply excessive force to avoid damaging the hinges. For maintenance, wipe the hinges regularly with a clean, dry cloth to keep them looking good. If you notice any rust or dirt, you can use a mild cleaner and a soft brush to clean them. Also, check the screws periodically to ensure they're still tight.
