Abstract
Abstract An apparatus for leveling and adjusting the height of household appliances. A nut or similar device is mounted on the appliance frame for receiving an upright weight supporting bolt. The bolt rests on a flat arm, which in turn rests on the floor or supporting surface. One end of the arm is attached to the frame and provides a low friction surface for contact with the bolt; thereby, substantially all lateral forces derived from sliding the appliance across the floor are absorbed by the arm and not transmitted to the bolt.
