Environmental protection for lowerable pole
An environmentally robust joint for use in a lowering pole assembly comprising a lower pole section and an upper pole section. The joint includes a lower adaptor comprising a lower pivot member defining a first central wiring passage and an upper adaptor comprising an upper pivot member defining a second central wiring passage communicating with the first central wiring passage. The upper pivot member is rotationally coupled to the lower pivot member, and sharing a common axis of rotation. At least one of the lower adaptor and the upper adaptor comprises a pole adaptor mounted at an operative angle to the axis of rotation. The pole adaptor includes an open end for receiving an end of a pole section, and an internal wiring tube communicating with the first central wiring passage and the second central wiring passage.
