1. A method of catching a dropped vertical tubular, the method comprising:
contacting a clamp, carried by a tubular, by a roller, as the tubular on which the clamp is attached falls at an uncontrolled rate;
guiding the roller, by the clamp, in response to contacting the clamp, towards a rotatable plate supporting the roller;
interfering with the roller and the clamp by the rotatable plate in response to guiding the roller; and
ceasing the uncontrolled fall in response to interfering with the roller and the clamp.
