ABSTRACT:
A pole top safety device in general comprises a housing including an inner sleeve member dimensioned to fit over the top of the utility pole. A securing mechanism for selectively securing the inner sleeve member onto the utility pole at least at a point below the top of the utility pole. An outer sleeve member is positioned around the inner sleeve member, with the outer sleeve member being rotationally supported on the inner sleeve. The outer sleeve member carries a beam member extending outwardly from the outer sleeve, with the beam member including attachment means at its distal end to which a fall arrest system is selectively attachable. Particularly, the beam member extends radially outward from a position adjacent the utility pole, with the safety device and particularly the inner sleeve and associated outer sleeve being attached to the pole at points both above and below the beam member. The arrangement provides a support structure for a fall arrest system which provides a rated anchor point for a retractable lifeline in compliance with regulatory standards. The device allows rotation of a lifeline 360.degree. around the utility pole with little effort, and is easily installed and removed from a utility pole without extensive setup. The device is also configured to withstand the adverse affects of the outdoor environment.
