During each use
It is important to regularly monitor the condition of the
product and its connections to the other equipment in
the system. Make sure that all pieces of equipment in the
system are correctly positioned with respect to each other.
WARNING, be careful to:
- foreign bodies which can impede the operation of the cam,
- situations where the safety catch can snag and cause the
cam to open.
Pull the safety catch down and lock it on the frame of the device.
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.
Removing the rope
Move the device up the rope while pulling the safety catch down
and out.

Compatibility

Verify that this product is compatible with
the other elements of the system in your
application (compatible = good functional
interaction).
Connectors
Make sure your connectors are compatible
with the rope clamp/grab (shape,
size, etc.).
Any equipment used with your rope clamp/
grab must conform to applicable standards
and regulations.
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.
