Brass Ball Feet provide a nice transition between table surface and base of item. Use on clocks, boxes, trays, lamps and more. Typically 3-4 feet per application are necessary to insure item is stable. Slight leveling can be achieved by loosening or tightening the depth screw is inserted into the wood. Large items or items with multiple legs may require more feet. Wood adapter screws are included to thread directly into wood. Brass has an un-lacquered natural finish which will darken over time. If a long lasting bright and shiny finish is desired brass must be cleaned and lacquered.
