This Storage does take 2 people to install and it was built fine for a small shed.  Where we give it just a 1 Star is that it does NOT provide ANY loops or shelves or anything to hang any items you would place inside.  Other than coming up with my own idea of using a Super industrial Velcro and cutting belts or some other material you have nothing.  You can place a couple corner stands inside & we ordered 2 of them.  JUST have Wasted space!  I would not order this again.
