This heavy-duty aluminum flagpole can be "telescoped", allowing flags to fly beautifully at varied heights. The anodized aluminum sections lock into place with our heavy duty stainless steel pin. The Heavy Duty Telescoping Flagpole comes fully assembled and has 4 moving sections. The diameter of the pole, the gauge and thickness of the aluminum make it the strongest telescoping flag pole in the industry. These Heavy Duty Telescoping Poles are made in America!
