Quoted from OLDPINGUY:I wonder if these separations are occurring by pulling or pushing the cabinet on a floor,
as opposed to lifting and moving?
I wondered that too, but one guy said he set his up and never moved it yet it split.
FYI: Don't drag your machine around.
If you have to drag it, use magic sliders and have a person in front and a person in back holding on to the legs not the cabinet.
Best option is a pinball lift which I do not have either, but I've been seriously looking at them after all this drama.
Thankfully my Premium cabinet is still fine with no cracking or separation.
