Abstract
A rack for transporting workpieces through electrostatic coating operations. The rack includes a pair of vertically extending, rectangularly cylindrical hollow tubes having apertures formed in their front sides. A support hook has a workpiece engaging portion, offset portions extending from either end of the workpiece engaging portion, and contact portions extending from the ends of the offset portions, with each adjacent portion of the support hook extending perpendicularly to its adjacent portion. The support hook is manually engageable with the tubes by insertion of the contact portions of the hook into the apertures of the respective tubes. The hook is cantilevered to the tubes, with the workpiece engaging portion spaced from the tubes. The tubes shield their interior surfaces and the contact portions of the support hook disposed in their interiors from the sprayed particulate. Objects hung from the workpiece engaging portion of the hook biases the shielded contact portions of the hook against the shielded interior surfaces of the respective tubes to assure good electrical contact between the support hooks and the tubes.
