This tent is a hybrid of a traditional frame tent and a structure tent. With no center poles, your square footage is uninterrupted allowing for a multitude of different table layouts. The clear trac tent has a less extensive top framework, creating a more contemporary look. Not only does this tent have less poles in the framework, it has less poles around the perimeter. A traditional frame tent has poles every 10 feet. This tent only has perimeter poles every 20 feet. Optional lights and clear sides are available with the tent. The sides easily slide open and securely close.
