Square Straight Hinged Aluminum Poles

The lighting standards listed here are designed for ground-mounted applications. Standards mounted on structures require factory consultation — contact our Inside Sales team for exact catalog numbers and pricing of such poles.


Pole Shaft

The shaft is extruded from all new 6063 alloy aluminum tubing and heat treated to produce a T6 temper. It is gracefully cone tapered to the butt diameter. These standards may be drilled to accept side arm mounted luminaires. Mounting orientation must be provided. An aluminum tenon may also be supplied as standard.

Hinged Base Casting

Cast from A356 alloy aluminum, the anchor base is heat treated to produce a T6 condition and inserted into the anchor base casting. The two pieces are joined by a continuous circumferential weld at the outside top and inside bottom of the anchor base. The base has a hinge pin to allow lowering of the pole to maintain luminaires.
