I've used this set-up for double booths, 10x15s, or single booths in a wide variety of configurations.
These panels all have telescoping legs, which is great for leveling the walls on a hill (Park City) or onto a curb (Madison)! This is the inventory:
38.5" W - 11
30" W - 2
18" W - 2
Banner Bar - 1
Long support bar - 2
Short support bar - 2
Telescoping support bar - 1
Box of misc. stiffeners for joining panels (straight, 90degree, and T-shape)
More cable hangers and hooks than you will likely ever need, along with the roll-up bags for them.
I'm sure there are other extras that I can't think of at the moment, but it can all be yours!
Purchased new, this complete set-up would be just under $3K. $800 is a steal!
Will entertain the idea of meeting someone midway between Santa Cruz and wherever YOU are in within the SF Bay Area or Monterey Bay Area!
