14. A method for performing a subterranean operation, the method comprising:
moving a tubular into an opening in a torque wrench of an iron roughneck;
rotating the torque wrench, thereby activating a stabbing guide;
engaging the tubular with a plurality of guide elements of the stabbing guide in response to rotating the torque wrench; and
moving the plurality of guide elements radially inward toward a center axis of the stabbing guide a radial distance that is proportional to a distance of rotation of the torque wrench.
