Bases for 3” Diameter Sign & Light Poles

Cast aluminum ornamental post bases for our 3" diameter sign posts and outdoor street lighting poles are both decorative and protective. They are rustproof, solid cast aluminum, and are very durable. Select one of our unique base styles below to fit both our 3" & 4" diameter post options shown above. These cast bases can either slip over (solid base) or wrap around (split base) the post for easy installation. Bases are then secured to the post with the provided stainless setscrews that lock the decorative post base in place.

  • Solid cast aluminum post base provides a durable classic look
  • Clamshell or slipover base design for easy installation and refinishing
