Iris MCB L tubs

[blkstrliner]

Hello, I'm trying to replace my tubs from a reptile basics iris sweater box rack.

all the websites I have found using the "MCB L" model, have different measurements.

None of the measurements match up with what is printed on the original label found on the tubs that came with the rack.

the only thing I find common is "MCB L"

even the quart size is different.

My Original tubs say 30.6 quarts.

the iris web site say 33 quarts yet use the same MCB L name.

should I ignore the mismatched measurements (maybe everyone measures differently)?

any advice is appreciated.

I recently picked some of these up at Office Depot. Measurements without the lid are 23 3/4 l, 16 1/8 w and 6 high. The label states a larger size because that's with the lid on. It also says 33 qt
