Using your Deltana left - handed 5 x 3 - 1/4 hinge is easy. First, find the right spot on your door or cabinet where you want to install the hinge. Make sure it's lined up correctly. Then, use the #12 x 1 - 1/4' wood screws provided to attach the hinge firmly. When opening and closing the door or cabinet, the hinge should operate smoothly. As for maintenance, it's a good idea to clean the hinge regularly with a soft cloth to keep it looking nice. Avoid using harsh chemicals as they might damage the brass finish. If you notice any looseness over time, simply tighten the screws. This hinge is made to last, but taking good care of it will ensure it serves you well for years to come.
