Abstract: An apparatus for providing a guard against electrical shock near an insulator carrying an energized, exposed conductor. In particular, this apparatus is intended for providing protection from electrical shock by providing a slotted insulator cover having means for moveably coupling a line guard thereto, said coupling means comprising a slotted ball and socket arrangement connected to the insulator cover and having a line guard adapter secured to the moveable portion of the ball and socket arrangement. By varying the degree to which the socket covers the ball, the degree of movement of the line guard adapter is defined. By closely fitting the socket to the ball, the insulator cover can be secured to the insulator by disaligning the slotted portions of the ball and socket.
