SB1 (Beam Arm) Carbon Steel
Anchor bolts conform to ASTM F1554 Grade-55 standards. Bolts have an “L” bend at one end and a minimum of 12” galvanized threads on the other end. Two galvanized flat washers per ASTM F436 and two galvanized hexagonal nuts per ASTM A563 Grade DH are provided with each bolt.
The base plate is fabricated from ASTM A36 carbon 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.
Each pole assembly is fashioned with a direct embedded base. The base extends below the ground line and is fitted with a 1 inch coupling located 2’ below the ground line for wire entrance. The direct embedded base is fashioned with an anti-rotation bearing strap on the bottom of the base.
The pole shaft conforms to ASTM A1011 Grade 50 carbon 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.
SB1 arms are fabricated from the same material as the pole shaft. SB1 arms are fitted with a 2.38” x 6” pipe adapter for luminaire mounting. Arms are cut with a 45° angle at the arm base and are circumferentially welded to a mating cut on the pole shaft.
Carbon steel poles may be specified as hot-dip galvanized per ASTM A123 and/or finish painted with our standard Millerbond Wet Coat Finish.
All hardware and fasteners are supplied with each pole assembly. All structural fasteners are galvanized high-strength carbon steel.
