Product Overview
Pole Shaft - The pole shaft is extruded from seamless 6063-T6 aluminum.
Pole Top - A removable top cap is provided for poles receiving drilling patterns for side -mount luminaire
arm assemblies. Other pole top options include Tenon Top, Top Cap Only or Open Top which is typical
when the pole top diameter matches the necessary slip -fit dimensions.
Hand Hole - 2" x 4" oval hand hole and grounding provision are provided (dimensions are nominal).
Cover and cover attachment hardware also included.
Anchor Base & Cover- The anchor base is cast from 356 alloy aluminum and supplied with an aluminum
two-piece base cover. The completed pole assembly is heat-treated to a T6 temper. Optional decorative
base covers available as special order.
Anchor Bolts - Anchor bolts conform to ASTM F1554 Grade 55 and are provided with two hex nuts
and two flat washers. Bolts have an "L" bend on one end and are galvanized a minimum of 12" on the
threaded end.
Hardware -All structural fasteners are galvanized high strength carbon steel. All non-structural fasteners
are galvanized or zinc -plated carbon steel or stainless steel.
Finish - Finishes include anodized or painted. Please consult factory for special finishing colors and
fixture matching options. When storing light poles outside, remove all protective wrapping immediately
upon delivery to prevent finish damage.
Design Criteria - Standard EPA (Effective Projected Area) and weight values are based on AASHTO
Criteria (with 3 second gust factor) for side and top mounted fixtures only. Satisfactory performance of
light poles is dependent upon the pole being properly attached to a supporting foundation of adequate
design.
