Using these Deltana adjustable hinges is a breeze. First, gather your tools like a screwdriver. Find the right spots on your cabinet or door frame and attach the hinges using the #7 x 3/4 wood screws. You can adjust the hinges easily to make sure the door aligns perfectly. As for maintenance, just wipe them with a soft, dry cloth regularly to keep them looking shiny. Avoid using harsh chemicals as they might damage the finish. In high - traffic areas, check the screws every few months to ensure they're tight. That way, your hinges will serve you well for a long time.
