This 10" 3 chord truss aluminum truss has been painted black to match the black logo signs for this display. These displays are used in pairs at trade shows and conventions around the globe. 20' x 20' truss structures are by far one of our most common trade show booth sizes and can be found in most exhibitions and fairs. The ease of use and portability of aluminum trade show booths make Exhibit and Display truss a standard in the market. Fast easy and ready to perform.
