Important Note About Using 4x3 Units Within A 10x10 Space. The Standard Popart Fabric Units are based on Metric Sizing. As a result, the Standard 4x3 units are 124.5"w, 4.5", beyond the typical 10x10 tradeshow space. Historically, 4 Quads wide by 3 Quads high display units have been used in 10x10 spaces at trade show exhibit halls. To accomodate the trade show environment, a special non-metric based, 4x3 U.S. Frame was developed. The 4x3 U.S. Frame is 117.5" wide and fits perfectly within the required space at most exhibit halls.
