10 Foot Aluminum Square Straight Direct Burial 4in .125 Thickness

10' Square Straight Aluminum Direct Burial Pole, 13' Overall Length, 4" Square. The ALS-ASQS-4101-DB is a 10-foot square straight aluminum light pole designed for direct burial (DB) installation. Instead of using an anchor base and bolt circle, this pole is set directly into the ground (with embedment/backfill and/or concrete per local practice), making it a practical option for projects that want a clean look and simplified foundation work. With a 10' mounting height and a 4" square shaft, this pole is a strong fit for walkways, entrances, courtyards, perimeter paths, and small site lighting where you want a little more height than an 8' pole while still keeping the layout pedestrian-scale. The square straight profile is also commonly used when you want architectural consistency with square fixtures, brackets, or site elements. Because this is a direct burial pole, the overall length is longer than the mounting height to provide the below-grade embedment needed for stability. This model has a 13' overall length, allowing for typical installation depth while maintaining the specified mounting height above grade. For wind-load planning, it is rated at 4.5 EPA @ 120 mph—confirm the combined projected area of the luminaire, bracket/arm, and any accessories stays within the pole’s EPA rating and verify embedment depth and soil conditions per local requirements.
