150 Gallon Rubbermaid Stock Tank & Custom OOAK Drain Plug Water Heater Deicer
Seamless construction and reinforced ribbing for outstanding added durability and strength. 1-1/2" oversize drain. The heater is fairly new and worked great last winter, we custom shaped it to be closer to the bottom of the tank (see photo) because the way they are designed from the factory they set about 3 to 4" above the bottom and we didn't like the idea of the horses drinking the water down far enough to expose the heater coils and burning it out so it now is closer to a 1" clearance.
