Abstract

An apparatus for gripping a tubular for use with a top drive includes a connector at one end for rotationally fixing the apparatus relative to the top drive; one or more gripping members at a second end for gripping the tubular; an actuator configured to move and hold the gripping members in contact with the tubular; and a lock coupled to the connector for preventing the apparatus and the top drive from rotating independently of one another.
