In exceptional circumstances, continuous vibration due to abnormal wind conditions may lead to fatigue cracks at the welded connections. Typically, at the pole base or hand-hole opening adjacent to the weld.
As a preventive maintenance measure, it is recommended that poles and fixture arms be inspected on a regular basis. If a pole experiences excessive vibration, or if crack(s) is detected at the welded connections, immediately consult your agent or call 1-866-874-8889 (www.novapole.com)
