#1  The instructions are absolutely terrible.  #2  It takes way too much assembly even with decent instructions.   #3  The OVERALL height as stated on the website is NOT 84".   That's just the doors themselves.   Add another 6-7" for the railings and such.  This needs to be clarified somewhere on the website.  (It will not fit on my 86" high ceilings in my basement)  #4  Some of the pilot holes were not pre-drilled into some of the pieces.  #5  Good luck is you decide to waste your money on the doors.  I would not buy these again, mostly due to the terrible assembly instructions.
