Abstract: Rigid dangler cathode assemblies for use in a conventional, rotatable electroplating barrel are disclosed which remain relatively stationary in position within the barrel as the barrel is rotated in an electrolyte solution in which it is immersed. Each of the assemblies includes an L-shaped rod having a vertically extending end portion which lies within a guideway of a hanger arm rotatably attached to the outer barrel end wall and a horizontally extending end portion which projects through a hub in the barrel end wall into the interior of the barrel. A disc-shaped weight is slippably mounted offcenter on the rod within the barrel, which weight has a center of gravity below the rod.
