YOUR CART IS CURRENTLY EMPTY
The wheeled carry case is the travel and storage half of a SuperWall. The wall packs into the case, the case rolls, and the whole lot moves from the car to the stand without anyone carrying it down a service corridor by hand.
Between shows it earns its keep in a different way. Kit left loose on a shelf gets knocked about, scuffed and half lost; kit stored in its own case comes back out in the state it went in.
Worth having if your SuperWall travels more than once or twice a year, or if the people setting it up are not the same two people every time. Enquire through the form on this page for details.
