18 Foot Aluminum Square Straight Anchor Base 5in

The ALS-ASQS-5183-AB is an 18-foot square straight aluminum light pole built with an anchor base (AB) for bolt-down installation to a concrete foundation. Aluminum poles are a practical choice for projects that want a clean architectural appearance, corrosion resistance, and lighter handling weight than comparable steel poles, especially in outdoor environments where long-term durability matters. With a larger 5" square shaft, this model is a stronger option for mid mounting-height applications such as walkways, entrances, pedestrian areas, and small site-lighting layouts where fixture size, bracket loading, or wind exposure may require more pole capacity than a 4" shaft. The anchor-base design allows the pole to be set plumb on the foundation and serviced or replaced later without excavation. For wind-load planning, this pole is rated at 2.9 EPA @ 120 mph and uses a 10.5" bolt circle. Keep the total projected area of the fixture, brackets, and accessories within the pole’s EPA rating, and confirm foundation design per local requirements.
