Abstract

Abstract An electrically conductive rack or frame for transporting and supporting workpieces to be coated, and wherein the workpieces are in electrical contact with and supported on readily removable hooks that are electrically connected to and supported on the frame of the rack. The workpiece-supporting hooks are detachably engaged in struck-out, die-stamped sockets formed in the rack. The rack is also provided with die-stamped locking projections which prevent the hooks from becoming accidentally disengaged from the rack. A removable cover further safeguards the electrical connection between the hooks and the rack and prevents an undesired accumulation of coating material on the interconnecting portions of the hooks and rack.
