Dowco Heavy Duty 2 Pole Boat Cover Support System Includes 4 extra long straps with web loops at 1 end, allowing up to 14ft of reaching distance from the pole. Includes 2 premium heavy duty poles with locking levers, allowing an adjustable height of 32" to 57.5". These poles are extra strong, providing much more holding power than the basic twist lock poles. There are 2 pole top caps that are used to help distribute the load and provide a connecting point for the straps. These caps have quick release buckles already attached for easy tear down and setup in between uses. An extra long 12ft strap is provided to connect the 2 poles together. A detailed instruction sheet is included to assist in installation.
