The 20 x 40 Center Pole Set comes with three (3) 14' Anodized Aluminum four-piece center poles. This four piece 14' Aluminum center pole is often used with 20'-wide and 30'-wide Pole Tents. Our 2" diameter, 4-piece aluminum center pole is a portable, lightweight option. Aluminum is highly resistant to rust which will extend the life of the pole and prevent staining on white vinyl.
