Using the Deltana 3 - 1/2 x 3 - 1/2 x 1/4 Radius Hinge is easy. First, make sure your door and frame are clean and dry. Then, attach the hinge to the door and frame using the provided #9 x 3/4' wood screws. When opening and closing the door, you'll notice the smooth movement thanks to the ball bearing. For maintenance, wipe the hinge with a dry cloth regularly to keep it clean. Avoid using harsh chemicals as they may damage the finish.
