Don't know if it was mentioned, but there was a few hundred dollars of extra product provided and delivered to accept the rack as it were.
Still can't be 100% sure it was a fault/defect, and if so, the whole rack was not faulty, it would have been the end plate on just 1 post or 1 crossbeam, which could have been replaced if absolutely required to function.
The rack is perfectly functional now and as mentioned, agreed compensation for time and minor adjustment to rack was provided.
