I recently won a Kennedy versa cart from a local auction and when I picked it up the ball bearing drawers were opening on their own. I searched many places and didn’t find a solution. I pulled a few drawers off their rails and noticed black rubber chunks in some of the drawers and in the bottom of the box. After searching on Kennedy’s site I discovered these were rubber detents that the drawer slides slip into to secure the drawers. Ordered about 20 and popped them on. Instant fix! Also had to remove the lock to get the code which was a PITA. But a cheap fix through easy keys. Unfortunately both boxes do not use the same key !!! So I get to take that one off as well
