Thank you for viewing. Ellisse Aluminum Tarp Pole Red, 32mm diameter x 185-215cm length Includes two separate middle poles (sold separately), giving you two sets of poles. There is some evidence of use. These poles are thick and sturdy, suitable for all types of tarps: poly, polycotton, and cotton. With this thickness, you can securely set up even large tarps. Basically, with two poles, you can do some arrangement and setup, so I think it's a good deal to buy them together. Thank you.
