They can contact me (Jane Riffle) at nordkyn@nordkyn.com or 253-847-4128 days. The price is negotiable and will sell parts if no one wants the whole set up. The chute is designed to be supported by rods that go up and over at each end so there is nothing balancing on the ground. Bob designed it so that you could hang banners on the end supports. You probably have seen it at one time or another. Been around a long time but being chain link still in good shape.
Approximately $1000.00
Includes Weight pull Cart - meets IWPA requirements

Sling scale
About 3000# +/- blocks
Loaner harnesses full range of sizes
It does show a banner up at one end and does show some of the stantions and bases that we used with rope to delineate holding areas and crowd control. 
There is a platform scale that could also be
available but is owned by my husband. He would want $200.00 for it.
