A pole system comprises a shaft that includes tracks for mounting luminaires, street signs, bicycle racks, decorative signage, banners, traffic signals, pedestrian signals, or other items. In one embodiment, a pole system includes a shaft with two or more vertical tracks. Each track may have a dovetail shape and may be configured to receive mounting nuts for mounting items to the shaft. One or more vertical raceways separate from a center opening of the shaft may also be present. |
