The Kara-Acht-Schlinge serves as a backstop when a rope should block in one direction (load rope) but slide in the other direction (pull rope).
application
The Kara-eight loop is used in the tackle as a backstop if no two identical snap hook for a construction garda hitch are available, but a carabiner and a figure eight . The load rope is blocked after each lift. The deflection or pulley can then be shifted for a further lift, and longer lift paths must also be managed when lifting loads.
The Kara-eight loop is like the garda hitch in the mountain rescue in the crevasse rescue on glaciers and in the high-altitude rescue used, for example, when Swiss tackle , in which self-pulley or Münchhausenplatz technology .
Knot
A figure eight is hooked into a snap hook. The rope is put as a loop through the figure eight from behind, the loop is then hooked into the carabiner from the front. Now the loop is twisted to one eye so that the load rope is in front. This eye is slipped over the carabiner and then hooked into the carabiner. The snap hook is hooked into a sling .
The load can be lifted on the pull rope (which is pulled, which should be movable, sloping out in the picture below). If the pull rope is relieved, the load rope clamps the pull rope and blocks it.

Alternatives
- If identical carabiners are available, the Gardaschling is preferable as a backstop.
- A mechanical backstop is the cable clamp (breast clamp) or the ascender .
- There are also pulleys with built-in backstops.
- The Tibloc is particularly lightweight but less gentle on the rope .
