If you know your max dimensions, but are unsure of the capacity you're looking for... Length x Width x Height / 231 = your tank capacity (give or take a few gallons) Shapes: "R" = Rectangle - "R/O" = Rectangle/Odd - (click the blue tank # to see the R/O shape. Odd shaped tanks are not available online) |
The dimensions are indicated in inches and are calculated as exact as possible. However, due to the nature of the Roto-Molding process and the physical properties of plastic, a slight swelling and shrinking may occur. Please keep this in mind if your project demands close tolerances. There is no Height, Width or Length noted on this list since the holding tanks start bank and can lay in any configuration you need. |
Holding Tanks Are Exempt From Any Free Shipping Promotions
