Abstract
A cathode frame for an electro-chemical apparatus, such as an electroplating tank, is provided with a plurality of contactors removably attached to the electrical conductor bar in order to be discarded and readily replaced by another contactor after the plating material "builds-up" on the contactor to a condition where the plating inhibits electrical conductivity.
