Petey- that's so neat!  Do all of your lower or do you have to use a ladder for the one?  My shop is in a pole barn with no ceilings.  I'm thinking of how to attach supports for horizontal storage on a interior wall. Not sure of the inner construction as it is there to separate our workout room.  🤔 

I looked at Monster Rax and they look like a great solution in the right setting.
