Im gathering thats the ebay special?
Thats the size i have in my 82L pot, and its snug, its pushed all the way to one side, but it works
a word of caution tho... I think 22kg of grain is the absolute upper limit. I did a RIS with 22kg and it was interesting. tho we still got ~70% efficiency and less than 1L of trub at the bottom of the kettle (recirc)
