The best thing with this rack is that you can also use the 28 qt sterilite tubs too. 2 tubs per level, that's 18 tubs or even 20 if you use the top most level with covered tubs.
This rack also has a smaller version at home depot where you make into a hatchling rack. I used 4 6 qt tubs with cover per level. I just used the tub covers so I don't have to put the board under the shelves. This is my temporary hatchling set-up. A friend of mine used 4 v-18 tubs per level and it fit perfectly. That's my next project.
