Using the Deltana Spring Hinge is easy. First, make sure the door and frame are clean and free of debris. Then, attach the hinge to the door and frame using the provided #9 x 1/2 machine screws and #9 x 3/4 wood screws. Once installed, you can adjust the tension of the hinge to suit your needs. To keep the door closing smoothly, you may need to adjust the tension from time to time. When it comes to maintenance, simply wipe the hinge with a clean, dry cloth regularly to remove dust and dirt. Avoid using abrasive cleaners as they can damage the finish. If you notice any loose screws, tighten them right away to ensure the hinge stays secure. This hinge is built to last, but following these simple steps will help it serve you well for a long time.
