3 odd road cases btz accepted

3 thin long road cases. Maybe a pop up back wall but dont know. Seems like weighted bases and poles. No instructions. The cases themself: Great for trade shows art shipping and other stuff you want in a super heavy duty case. There is some bits in it, no time to figure it out. Maybe a pop up display or tri pod of some sort. Come see it and make an offer at 391 attwell drive during monday to friday 730am to 430pm the cases are probably worth more then the poles and stands.
