Twin Tube Plus... all of the great features of the Eureka! Twin Tube System PLUS so much more. Engineered with an easy to assemble, stronger, keder-style frame and new top design allow the tent to be installed with fewer people, yet faster and safer than traditional frame systems. The sliding keder system on the top and sidewalls helps speed up installation and allows for increased tension on the fabric for better appearance and enhanced HVAC options. When your customer wants all of the benefits of a clearspan, and you want a proven frame system from the manufacturer you know and trust... ask about Eureka!'s Twin Tube Plus.
