Wow.
I'm surprised they didn't come down, observe the problem, tell you to only put 2 on the shelves, pat themselves on the back, and claim success.

I don't think calling that a mistake even comes close to describing what they did. If they would have run their plan by either the clamp truck vendor or the racking vendor, this almost certainly would have been caught. And even without outside input, why they wouldn't at least just buy and set up a couple sections of rack as a test before doing the whole warehouse is beyond me. Unfortunately the type of people that make this level of bad decisions tend to not learn from their mistakes-or even acknowledge them.

Anyway, thanks for the input. Once they got the beam widths right, did everything work OK?
