I bought 3 large plastic carts to use to store tools in, and assembled 2. I left the other cart against the wall in the box. The carts were about $180 each and carry 600lbs. We needed the 3rd cart, and when we opened the box, we discovered the wrong hardware was included, so it was not possible to assemble the cart. A 60 mile (120 round trip) trip to Northern tool to obtain the correct fastners was unsuccessful and I did not experience any form of customer satisfaction, given the high prices of these tool carts. Calling the corporate office was another waste of 1 hour of my life, as well.
