Using this Deltana hinge is easy. First, make sure you've got the right left - handed hinge for your project. Whether you're working on new cabinets or replacing old hardware, start by aligning the hinge on the door and cabinet frame. Use the #7 x 3/4' wood screws provided to secure it in place. Make sure the screws are tightened properly so the door can open and close smoothly. As for maintenance, wipe the hinge with a soft, dry cloth regularly to keep it looking good. Avoid using harsh chemicals or abrasive materials as they can damage the finish. If you notice any looseness over time, just tighten the screws a bit. This solid brass hinge is built to last, but with a little care, it'll serve you well for years.
