This product is a piece of junk.  I spoke to the factory rep and he admitted that sometimes there are problems assembling this unit.  The panels are pre-drilled and the holes do not align.  The fasteners supplied fail to hold the pieces together.  Even at half price this unit is over priced.  I want to return it.  The card board packaging has been discarded.  The file cabinet should also be discarded.  I chucked it, all good.
