Three different sized Rubbermaid stock tanks

Rubbermaid makes three of the most popular agricultural watering stock tanks on the market. They are made from structural foam polyethylene and are found across the US and outside. They come in 100 gallon, 150 gallon and 300 gallon volumes. You can see below the differences in size. The 100 and 150 gallon stock tanks are similar in size with the 300 gallon clearly being much larger than the others.

Rugged Stock Tank Liners are offered in 4 sizes, from 70 gallon through 160 gallon stock tanks. Only the smaller two Rubbermaid stock tanks, the 100 gallon and the 150 gallon fit this range and can be covered by Rugged Stock Tank Liners. We do not presently make a liner for the Rubbermaid 300 gallon stock tank. 

Below you can see the size comparison of the two stock tanks.  

The 4ft/100 gallon stock tank liner fits the 100 gallon Rubbermaid stock tank.

The 5ft/130 gallon stock tank liner fits the 150 gallon Rubbermain stock tank.
