New in Box - Drain Plug De-Icer by API Designed for Rubbermaid stock tanks Use your water tank for your horses in the winter - installs in the drain plug opening, keeping the cord out of the water and preventing your comic horse from tossing it out. This is in the original box, never used. A little dusty from sitting in my tack room. Retails for $61.95 at Valley Vet.
