Dowco Heavy Duty 1 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 1 premium heavy duty pole with a locking lever, allowing an adjustable height of 32" to 57.5". This pole is extra strong, providing much more holding power than the basic twist lock pole. A pole top cap is also included to help distribute the load and provide a connecting point for the straps. The cap has quick release buckles already attached for easy tear down and setup in between uses. A detailed instruction sheet is included to assist in installation.
