Abstract: An upstanding valve body assembly is provided defining a center axis and includes radially expandable and retractable slips. The assembly includes a slip actuator rotatable relative to the remainder of the assembly about the center axis for expansion and retraction of the slips responsive to rotation of the slip actuator in opposite directions. A suspension member projects above the actuator and is threadedly engaged therewith for threaded shifting relative thereto along the axis. The suspension member is threadedly disengageable and engageable with the actuator portion upon rotation relative thereto in first and second directions, respectively.
