Tired of the normal octa-shell scheme? Spruce up your shell scheme with a maxima system instead. The same versatility as a booth shell scheme, but with a different, sleek look. The Maxima system is an Octanorm Patented design and is used throughout the world in exhibition displays. It is THE standard for upgraded system booths. Centrex can help you design a rented maxima booth. The Maxima system comes in two sizes – 40mm or the larger 80mm.
