All TRIO and CLASSIC Traditional tent covers are available in either a single piece or expandable design. Expandable covers have the versatility to extend the standard square tent to lengths over 100-ft. The diagram shows how the loops from the extension fit through grommets on the main tent cover and then loop-lace together. A vinyl flap then covers the lacing for a clean, seamless look. An expandable cover can ultimately save you money by purchasing one tent and having the versatility of a multi-sized tent. This feature can help accommodate you and your customers’ needs by providing the perfect size tent for any occasion.
