We run small enough parts that we can use two of these dividers per tank, which effectively gives us 3 tumblers in one. They're great for running multiple stages of media in the same tank or keeping heavy parts from pinging into each other when running. They basically triple our productivity! We have 5 tumblers with these dividers running 10+ hours a day and it took about 4 years for them to wear out. Well worth the investment!
