While climbing:

1. Belaying the leader dynamically

With the GRIGRI, the belayer moves in order to make it dynamic.

On a multi-pitch route, this movement is limited by the risk of hitting the station. A long lanyard gives the belayer room to move.

2. Belaying the second

The leader can climb light with a REVERSO, which is convenient for belaying the second.

Descending on a blocked rappel

The single rope must be installed with a blocking technique and a retrieval cord that allows recovery. Descending can be done with the GRIGRI or the REVERSO (with back-up device or knot).

Do not descend on the retrieval cord; it is used only to recover the rope.

Examples of blocking the rope

Risk of the knot passing through the quick link, even though it may appear blocked.

This technique does not allow descending on a single rope.

Blocked on a small quick link with back-up.

If the knot goes through the quick link, the fall will be stopped, but rope recovery will be complicated. Second rappel can be set up only after the rope has been fully retrieved.

Blocked with a large knot. Second rappel can be set up only after the rope has been fully retrieved.

Blocked without a rope-joining knot, with auto-locking carabiner.

Second rappel can be set up without threading the rope through the quick link. With a large quick link, risk of poor carabiner positioning and/or stuck rope.
