Plastisol coating, an excellent insulator can be applied to the sides or bottom of the anode as an additional option to prevent surface contact contamination thereby preventing any current barrier.

Anodes have cast-in mounting straps for a welded or bolted installation.

All weights and dimensions are nominal and subject to variation in material compositions and Jennings Anodes foundry tolerance.
