Replacement zinc anode

Kasco recommends replacing zinc anodes annually or sooner if the anode is reduced by more than 50%. Zinc anodes are available for 1/2" and 5/8" motor shafts.

For 1/2" and 3/4" HP units, the shaft size is always 1/2". For the 1 HP units, some use 1/2" shafts and some use 5/8" shafts. So you need to measure the diameter of the rod to confirm which anode is needed.

Warranty: No warranty is offered on this product as this is a product that is meant to deteriorate to elongate the life of the deicer in harsh conditions. 

In the diagram below, the anode is part B.
