POLES come in two styles. Cast tapered fluted poles are made of heavy wall cast aluminum for strength and durability. Extruded poles are made from heavy wall extruded aluminum and are available as straight fluted or straight smooth. Extruded poles are available as direct burial or anchor bolt mount. Cast tapered poles are anchor bolt mount only. BASES are a clam shell design allowing for easy access to wiring and inner base mounting hardware and are compatible with our cast and extruded poles.
