发明名称 NON-CONDUCTIVE THREE-SECTION EXTENSION POLE
摘要 An extension pole suitable for use in light bulb changing operations. The extension pole comprises first, second, and third telescopically intercoupled sections. A first locking assembly selectively locks the first and second sections to one another, and a second locking assembly selectively locks the second and third section to one another. The extension pole is made entirely of non-conductive materials to thereby reduce the risk of electrical shock to the operator.
