  • Patent number: 4171123
    Abstract: A conductor pulling device for pulling conductors through a conduit. A pulling member for independently receiving conductors consists of an elongated strip of material having a plurality of spaced openings therealong. The openings have a top portion which is larger than the bottom portion to provide a biting portion of each opening for biting into insulation disposed about a conductor when a portion of the conductor is inserted in one of the openings. The biting portion of the openings allows the conductors to be detachably retained to the strip while the conductors are pulled through a conduit. The elongated strip is connected to a fish tape by an aperture in the strip which receives a hook portion of the fish tape. Additionally, a hood made of organic polymeric material may be used to hold the conductors in place when the conductors are inserted through respective openings in the elongated strip and to reduce friction with the conduit.
