This rope clamp/grab is a device for
ascending rope. It slides along the rope
in one direction and jams in the other
direction.
The cam's teeth initiate a clamping action
that pinches the rope between the cam
and the frame. The slot in the cam allows
mud to be evacuated.

The cam then stays in the open position.
Put the rope into its place. Pay attention to the Up/Down indicator.
Push the safety catch so that the cam presses against the rope. In
this position the safety catch helps prevent involuntary opening
of the cam.
