An embodiment of the present invention comprises an apparatus for engaging with an outside diameter of a tubular comprises a device body having an internal surface that defines an internal diameter in a first position and allowing the tubular to pass therethrough and an actuator operable to move the internal surface of the device body from the first position to a second position, the second position defining an internal diameter less than the first position internal diameter. The internal surface of the device body is sized with a predetermined grip length for engaging with the outside diameter of the tubular, The grip length is determined by a function of the outside diameter of the tubular and the coefficient of friction between of the outside diameter of the tubular and the interior surface of the device body and the device body is operable to engage with a tubular having a predetermined range of outside diameters.
