  • Patent number: 6167988
    Abstract: A horizontal support member in the form of rod, pipe or tube is disposed transverse to and displaced from a rigid or utility pole proximate a messenger cable supporting a cable. The support member is supported on and a part of a projecting arm extending outwardly from a bracket attached to the utility pole. The support member is further provided with flanges on the ends thereof to prevent hooks on the end of a lineman's ladder from slipping off the ends of the support member. The support member is long enough not only to provide engagement for both hooks of the lineman's ladder but also could be extended so that the ladder hooks cannot slide off the support member as long as the hooks of the lineman's ladder are astraddle the projecting arm. The projecting arm is of sufficient length to position the top of the ladder below the front face of an electrical equipment cabinet which may be hung on and bolted to a pole bracket.
