They sent me a different wheel clamp than the one shown in the pictures. It had obviously been used, with bent parts, scratched paint, a different type of key than pictured that did not fit the lock, and crib packaging damaged. The locking mechanism was not the same as shown and entered the case freely. The whole thing was very dirty, hands only had to be washed when inspecting the room, sending it back. You're about to rent a trailer and want it to be secure when you're on site, that's too big a question mark to trust.
