I finally got a replacement that fas fine. Zoro shipped it via the same freight company but requested “extra packing.” The extra packing consisted of laying the box on its back.
Since it was on its back it was far easier to attach the wheels - unlocked the drawers, pulled out the wheels and the instructions and saw that the instructions are completely wrong.
While the instructions said to remove the bottom drawer, insert bolts and attach wheels, this chest had the threaded posts already attached to the bottom, so it was a breeze to attach the wheels.
Once upright (and half loaded), I found two steel reinforcements that I initially thought were drawer dividers seem to be drilled for the wheel posts - so a reinforcement.
Do I need to empty the chest, remove the wheels and add the reinforcements or should I be OK as is - the chest probably won’t be moved much.
FWIW, it is 440 http://www.protoindustrial.com/en/industrial-tools/Proto/Tool-Storage/Roller-Cabinets/a6a63be2-9b9a-4d06-be29-699bd7cd803f_Proto®-440SS-27"-Roller-Cabinet---12-Drawer%2C-Red/J442742-12RD_Proto®-440SS-27"-Roller-Cabinet---12-Drawer%2C-Red/
