1. A pulling device used to attach to a bundle of conduits, the bundle having a non-circular exterior profile, said pulling device comprising:
a distal end having a generally cylindrical exterior surface and an interior pocket to receive one end of the bundle of conduits, with at least a portion of the interior pocket having a non-circular profile, shaped to constrain a rotational orientation of the bundle of conduits within the pulling device, wherein the interior pocket has one open end and one closed end;
a pulling eye configured to allow the pulling device to be pulled through a bore hole;
wherein one or more apertures extend from the cylindrical exterior surface of the pulling device to the interior pocket, sized and located around the cylindrical exterior surface of the pulling device to receive a fastener or fasteners, where the one or more apertures are at one or more angles between positive and negative 60 degrees from normal relative to a central axis of the pulling device; and
wherein at least one of the one or more apertures is located such that each received fastener cuts through a sidewall of a conduit to attach the bundle of conduits.
