In the past some of the Axiom boxes I've received came with very loose straps. One came with 3 out of the 4 straps and a hole in the side (VP180). Have a feeling that the shipping guys use the straps to man handle those boxes. Bet the heavier and longer the item the more likely that a strap stretch and come off.

In any case I was lucky ... seems that you were not as fortunate ... and of course, as Murphy would have it, to a very expensive item ...
