Here is one of my posts from a different thread.

I thought I would transfer the tub information into the forums before it's lost. Animal Plastics racks use the 1752, 1754 and 1756. As most of you know Sterilite has discontinued some of these tubs and some are hard to find. The 1752 is hard to find, but the 1851 (Walmart) can be used in its place. The 1754 has been discontinued and replaced by the 1753 (exclusively at Target). The 1756 has also been discontinued and replaced by the 1755 (exclusively at Target). The new 1753 and 1755 have latches on them, which are easily removed. The tub then has a small gap (see picture below) that is 1/16" in size. As far as I can tell, this won't be a problem as long as your rack doesn't have a large gap. I have a 1754(10 shelf) Animals Plastics rack on order and will post more info when it comes. I am picking up some 1755 tubs this week and will post pics of the gap on them as well.
