  • Patent number: 10578233
    Abstract: A pipe pulling device guides extruded plastic conduit tubing through a building structure. The device has a fastener body including a main shaft supporting a resilient expansion sleeve thereon that can be inserted into an open end of the tubing. A nut is threaded onto the main shaft for axially compressing the expansion sleeve between the nut and a fastener head at the inner end of the main shaft to radially expand the sleeve within the tubing and frictionally grip the fastener body relative to the tubing. The nut is tapered outwardly and supports an elongate, rigid tip body extending longitudinally outward from the tubing to guide insertion of the tubing through cavities in the building structure. Various accessories can be secured to the nut or the tip body to assist insertion of the pipe pulling device through different building structures.
