Is that the drawers are interchangeable between different Sortainers.....I got a 4 Drawer Sortainer today for my birthday and made it my Kreg Jig Sortainer. Well I really didnt need the middle drawer between the two small ones so I took two small drawers from my 9 drawer and put those in the 4 drawer and turned it into a 5 drawer and the 9 drawer became a 8 drawer.....much more efficient for my needs.
