oil rubbed bronze finish ball lamp finial adds a charming accent to a lamp. This finial features a traditional knob shape. In addition to providing a decorative touch, the finial secures a lampshade firmly onto a standard table or floor lamp. To install, unplug your lamp and remove the old finial by turning counterclockwise. Then, place the lampshade over the lamp harp's threaded stud and fasten the finial by turning clockwise. This finial is 1-1/2 inches high.
