The base plate is fabricated from ASTM A240 stainless steel. The base is fabricated with slotted bolt holes to allow for a +/- 0.5” variance in listed nominal bolt circle size. The base plate telescopes the pole shaft and is circumferentially welded top and bottom.
Each pole assembly is fashioned with a Millerbernd Manufacturing Company High Base. The base is fabricated from the same material as the pole shaft and stands 27 inches tall. The pole shaft is slip fitted and welded to the base.
The pole shaft conforms to ASTM A240 Grade 201LN stainless steel standards.
A reinforced handhole with cover, grounding lug, and hardware is provided with each pole assembly. Pole assemblies fabricated with a High-Base are provided with a flush mounted handhole with cover, grounding lug, and hardware.

Each ST1 arm attaches to the pole shaft with a cast steel, mating 2-bolt simplex bracket (an optional cast steel, mating 1-bolt (1BS) simplex bracket is available. ST1 arms have a rise of 3 feet and 3 inches from the pole top and have a gradual, consistent upsweep throughout the entirety of the arm.
