摘要： A tool for facilitating the pulling of strands between spaced supports to which the strands are to be attached which consists generally of a handle with a grooved pulley mounted thereon and a rotatable key mounted on the handle adjacent the pulley which may be turned from an open position to permit placing a loop of the strand over the pulley to a closed position to prevent the strand loop from leaving the pulley when not in taut condition and the method of pulling strands using said tool which includes the steps of fastening the ends of strands being fed from storage rolls to one support adjacent the storage rolls, looping said strands over the pulley, pulling the tool with the strands looped over the pulley to a second support and finally fastening the strands thus pulled to the spaced supports.
