Thank you. That's what I assumed. I've seen online Jacobs chuck adapters for 7/16 quick chucks. So I figured I could use that on the rare occasion I need to you a bit that uses a traditional chuck.
I know this is old. But I wanted to say I agree with you. Just picked up a bunch of the tool cube boxes on clearance at princesses auto. I really don't understand why they are not more popular. I believe its awesome for a basement workshop organization.
