  • Patent number: 7216846
    Abstract: A connection apparatus and associated method are provided. The connection apparatus is configured to be connected to a guide line and a conduit so that the conduit can be pulled through a structure by the guide line. In this regard, the apparatus can include a body member that extends between first and second ends and defines a connector for engaging the guide line and an engagement portion for engaging the conduit. In some cases, a second connector is provided to engage a cable, such as an electrical wire, that is disposed in the conduit. Thus, the apparatus can be used to pull the conduit by a leading end thereof, and the apparatus can additionally pull the cable through the structure with the conduit, i.e., without requiring separate operations. The body member can also define a tapered outer contour, such as a frustoconical shaped end, to facilitate the passage of the apparatus and conduit through the structure.
