I bought a few because they were the only metal rolling boxes w a low enough profile (height) to fit under my current worktable.
the biggest issue is there are functionally two versions of the work box.
one version (cd-2204) has pin mounted casters on all four corners, two of which can lock, and detents that prevent drawers from casually drifting open, and from more than one drawer from opening at once.
the other versions (cd-2205 or 2207) have flange mounted casters, w crappier versions of wheel locks, which are mounted further inboard. They also have nothing to prevent any or all of the drawers from opening at once, easily shifting the center of gravity forward and toppling the box onto the floor.
I think my only current workaround is to stack washers on the open side to give it some back tilt, and use gravity to keep the drawers closed.
this makes a **** ad photo, but is a failure of design (or conversely, a win for the bean counters)
