ABSTRACT:
A metallic rack for holding workpieces to be anodized. The rack has a pair of opposed spaced apart parallel elongated clamp-supporting rack members and connecting cross-members. It is characterized by a longitudinal channel in each of the clamp-supporting members having openings of narrower width than the bottoms of the channels. The rack is used in combination with a plurality of pairs of acid-proof electrically non-conductive clamps in slideable engagement with the rack for holding the articles to be anodized. The clamps are characterized by foot members of cross-section corresponding to the cross-section of the channel in the clamp-supporting rack member. The clamp consists of a first frame member extending from the foot member, a second frame member extending from the end of the first frame member generally perpendicular thereto, and an operating screw comprising the moveable jaw of the clamp and acting in cooperation with the rack member functioning as the fixed clamp jaw.
