Using these Deltana hinges is easy. Just align the hinge with the door or cabinet frame and use the #7 x 3/4' wood screws provided to secure it in place. Make sure to pre - drill the holes to avoid splitting the wood. When installing, keep the hinge flat and level for a smooth operation. As for maintenance, you can clean the hinge with a soft, dry cloth regularly to keep it looking shiny. Avoid using abrasive cleaners as they may damage the finish. If you notice any loose screws over time, simply tighten them up. With proper care, these solid brass hinges will serve you well for many years.
