41qt Female Rack build

[ScottyBoa]

I did the same thing basically but I cut my shelves 17"x34.5" to make the tubs fit in there with no side to side play. Unless the OP's shelf is one where they aren't longways like mine, I don't know all I see are red Xs. Regardless, the exact width of the tops of the sterilite 41 qt tubs is 34.5".

Here is my 8 shelf unit.
