Abstract: An environmentally friendly fiberglass utility pole that comes in three sections that are telescoped one around the other to provide a strong, wind and bending resistant structure. Each of the three sections has alternating protruding and intruding surfaces that are slip fit together to provide maximum strength while conserving material. Additionally, each of the three sections preferably are different lengths such that maximum reinforcement is provided along the center of the length of the pole, without requiring excessive material (or weight) at the top end of the pole.
