The line between Portable Trade Show Exhibits and exhibits that are not portable has gotten a little fuzzy over the last few years. Since portables were first introduced back in the early 1980’s, they have been defined as displays that set up relatively fast and that ship conveniently as in UPS-able cases. Then along came truss exhibit kits. At first glance, they remind people of aluminum framed pop up displays, however they are nothing like the pop ups seen at so many trade shows.
