I have home made kind and I just found 41qt tubs locally in stock.. ( walmart never had the 41 in when I look so I happen to stopped by kmart with a friend and bang there 8 of them these are rubbermaid clear ( verus the sterile one s I been getting before) but i don't care if they fit my rack . I also seen they had about 40 more on a high shelf in another section ( i guess for quick grabbing when needed) so Iwill be set
