Autoblock

Prusik loop on the left and an Autoblock on the right.

Using an Autoblock is a climbing and caving technique used in rappelling and ascending.

An autoblock is a rope device that slides freely over the rope during a controlled descent, but jams in the descender in the event of a sudden drop or loss of control, stopping the descent. This prevents uncontrolled falls in the event of an accident in which the abseiler loses control of the rope.
