Eureka!'s Twin Tube frame system is a quantum leap beyond typical frame tent systems. Distinguished by its clear, unobstructed interiors up to 40'... its meticulously machined components... and its interchangeability with standard 2" frame components, Twin Tube is an incredibly rugged, attractive and versatile system that will impress your customers — and have you singing its praises too! Twin Tube offers advantages that other frame systems just don't have, like — superior strength in our double tube design. This translates not only to a cleaner look, but also a stronger frame and fewer parts to inventory, handle and transport. Twin Tube... the intelligent frame system... it's special in every sense of the word!
