Abstract
Abstract A metal electroplating rack coated with an insulating coating. The extremities of the rack has tips which are uncoated to provide electrical contact for a part being plated. The portion of the rack adjacent the tips has at least one opening through the rack, the opening being coated with an insulating coating such that a continuous coating is formed with the coating on opposite surfaces of the rack so as to prevent loss of adhesion of the insulating coating at the tip.
