Abstract: An apparatus is provided for simultaneously electrically grounding and mechanical securing an electric device to an overhead support which comprises a generally downwardly depending downrod attached to the support; a coupling for engaging the lower end portion of the downrod to an upwardly extending hub with the mutually interfitting walls of the downrod end and the hub coupled in a male-female jointed configuration; a pair of openings in opposite sides of each of the interfitting walls, which openings are aligned; and a rod extending through the aligned openings, which rod has a head at one end in contact with the outer surface of the inner of the downrod and the hub and a thread portion opposite to the head for engaging an internal thread of the opposite opening in the outer of the downrod and hub. The apparatus ensures electrical grounding continuity and at the same time establishes a secure mounting configuration.
