ABSTRACT:
A field completion tool including a open frame formed on the top end with a yoke including a centrally located threaded drive bore receiving a threaded drive shaft having a spigot thrust fitting on the bottom end thereof. The frame includes on the bottom end an oversized hex nut which forms a clearance bore that may optionally be threaded but which is of sufficient size to telescope over a plastic pipe projecting upwardly from the top end of a meter riser which is telescoped over the length of a plastic pipe projecting from an underground gas utility distribution system. The frame includes a handle for grasping with one hand and may be used to rotate the frame to thread the hex nut to couple the frame to the top end of the meter riser. The frame has a clamping means which blocks relative movement of the upwardly projecting plastic pipe relative to the frame. A drive shaft includes a crank for grasping with the other hand so that the shaft may be rotated to selectively advance the thrust fitting engaged with a spigot to drive the spigot into the free end of the plastic pipe. The clamping means may be released and the drive shaft further advanced to draw such riser up over the free end of the plastic pipe.
