These nested cups are designed to fit in both the small and large bins from the Dewalt TSTAK organizer. They will also fit in the Craftsman Versastack organizer as they are basically the same product only red. Additionally they will also work with the bins from the Dewalt Deep Pro Organizer. The cups fit in the TSTACK and Versastack drawers as you can see from one of the included photos. They WILL NOT work with the Tough System organizer bins.
These cups aren't exactly a remix of the DeWalt Tough System Organizer Nested Cups by Brandito. Those organizers inspired my Milwaukee Packout Organizer Nesting Cup which in turn inspired nesting cups for Ridgid and Husky organizers. Now I'm back full circle to Dewalt.
While supports aren't necessary, the transition and underside of the fins might get a little messy without them.
