We make these tank stands in our shop to fit the Minox Variable Capacity Tanks we offer. They use heavy-duty casters—two locking swivel, two fixed. The square base fits inside the tank's circular body for support the whole way round. If that doesn't make sense at first, draw a circle on a napkin. Then draw a square inside the circle so that each corner of the square is touching a point on the circle's circumference. If that still doesn't make sense, just trust us.

Larger sizes have a support bar running through the center as in the picture, while smaller sizes just need the square frame.

They are guaranteed to fit the Minox tanks we sell, but may not fit tanks from another manufacturer. Bear in mind that two tanks with the same volume may have a different height/diameter combo.

We can make these for any size tanks if you want us to custom make one for you. The price will likely be a bit higher since we have to work off custom dimensions rather than the "off-the-shelf" sizes here. Contact us for more info on having a custom dolly made.
