Abstract
A support block for stringing one or two cables simultaneously which is hung from an existing cable suspended laterally overhead, in which the cable-to-be-strung can be rapidly inserted, and on which the cable-to-be-strung rests prior to its being lashed to a utility pole. The temporary support block is raised to the existing cable by means of a layup stick or similar hand-held installation pole by a worker standing on the ground. More than one support block can be hung and cable suspended therefrom before the cable is pulled between one or more utility poles. The method of using several support blocks reduces the frequency with which workers must put tension on a cable in order to string it and enables the workers to keep greater lengths of cable suspended above potentially-damaging ground traffic and obstacles.
