Abstract: A mechanism for completely self-leveling all four legs of an appliance cabinet includes a polypropylene foot at each corner of the cabinet. Each foot is interconnected by a continuous cable for vertical movement in unison relative to the cabinet and to each other. Each foot has an elongated slot for receiving and blocking a wedge through the outboard side thereof. A locking cable connects the inboard side of each wedge to an adjusting lever at the front of the cabinet. After the cabinet has been leveled, the adjusting lever is moved to pull the wedges into locking engagement with the sides of their respective slots, thereby to lock each foot in fixed relation with the cabinet.
