20' to 50' Round Tapered 4-Bolt Anchor Base Standards

• 20' to 50' mounting heights
• For single or multiple luminaire mounting
• Luminaires may be mounted on tenons, brackets or shaft may be drilled to manufacturer's mounting specifications

SPECIFICATIONS

All aluminum alloys shall comply with metallurgical and mechanical properties set forth in the Aluminum Association Standards.

SHAFT: The shaft shall be spun tapered from all new seamless 6063 alloy aluminum tubing and shall be heat treated to T6 temper. Each shaft shall have a minimum 6" straight length at the top to accommodate the center hub of the appropriate Lexington flood light brackets or tapered arm. Alternatively, the straight section may be drilled for mounting luminaires or left open. All Lexington shafts shall be polished with fine grain aluminum oxide cloths, resulting in a high quality circumferential satin brushed finish. After finishing each standard shall be fully tire wrapped with neutral PH krinkle/kraft paper for protection in shipment.

ANCHOR BASE: The anchor base is cast from A356 alloy aluminum. The anchor base shall be heat treated to a T6 condition. The anchor base casting and shaft shall be joined by a continuous circumferential weld at the outside top and inside bottom of the anchor base. The completed assembly will be heat treated to T6 temper after all structural welding is completed. A356 alloy aluminum nut covers shall be included with each anchor base unless otherwise specified.

HANDHOLES: Standards shall include a peripherally reinforced flush covered handhole centered 18" above the bottom of the standard. The opening in the 5" and 6" diameter standard shall measure 3" x 5". The opening in the 7", 8" and 10" diameter standard shall measure 4" x 6". An optional 4" x 8" opening is available for 8" and 10" diameter standards.

ANCHOR BOLTS: Each standard shall include four steel hot dip galvanized anchor bolts each with two nuts, two flat washers and one lock washer sized to match the anchor bolts. A schedule of bolt sizes follows.

SPECIAL FINISHES: Natural anodize, duranodic, or painted finishes may be specified as an addition to the satin brushed finish. All aluminum parts and accessories shall receive a finish similar to that specified.
