ABSTRACT:
A hollow conical line-pulling carrier which is connected with the line being pulled by a connection on the interior of the carrier spaced upwardly from the base of the cone for pulling a messenger line through electrical conduit. The conical portion is made of extremely light-weight plastic, permitting it to be either blown through the conduit or sucked therethrough. Because the connection to the cone is spaced upwardly from the base, it permits the base of the cone to adjust to debris, imperfections, or water in the conduit without having the cone collapse and thus permit the messenger line to continue to be pulled through the conduit.
