Cathedral Window Tent Sidewalls are a great addition to any formal event. These multi-purpose items can help shield the sun, block out the wind, or keep your guests dry during the rain. The cathedral style windows add a touch of class to your party atmosphere. They go great with fans during the summer months and heaters during the winter. They are priced at $1.50 per linear foot and come in 20 ft pieces. Tents can be completely sidewalled or partially depending on the need!
