Using your Deltana left - handed 2.5 x 2 hinge is a breeze. First, decide where you want to install it on your door or cabinet. Make sure the surface is clean and flat. Then, align the hinge with the pre - drilled holes and use the provided #7 x 3/4 wood screws to secure it in place. It's designed for easy mounting, so you won't have a hard time. When it comes to maintenance, a simple wipe with a dry cloth every once in a while will keep it looking good. Avoid using abrasive cleaners as they can damage the finish. If you notice any loose screws, just tighten them gently. This hinge is built to last, but taking these small steps will ensure it serves you well for a long time.
