Abstract: An improved spacer clip for mounting on an anode header bar joined to and supporting a planar anode sheet in an electrolytic cell containing a plurality of anodes and cathodes provides improved protection against direct anode-to-cathode contact and maintenance of more uniform spacing between adjacent anodes and cathodes. The spacer clip, formed of a resilient electrically non-conducting material such as medium density polypropylene, comprises a central body defining a vertex, a pair of arms extending from the vertex adapted to fit over the header bar, and a pair of exterior wings depending from the arms and diverging to a maximum spacing coextensive with the ends of the arms and thence converging towards each other to terminate in ends substantially tangential to the supported anode sheet.
