Description
The In-line Figure-Eight Loop (aka Directional Figure Eight) is a loop knot. It can be made on the bight without access to the ends of the line. The loop can only be loaded in one direction or the knot may fail. It is useful on a hauling line to create loops that can be used as handholds. It also provides a place to attach a Z-Drag (a mechanical advantage system) to the line when Prusiks are unavailable.
Strength/Reliability
The In-line Figure Eight is secure if the load is properly applied. When a load is applied in the wrong direction the knot will capsize. In cases where the load might be applied in either direction, the Alpine Butterfly Loop would be a better choice.
Warning
Verify tying technique with a skilled instructor where knot failure could cause property damage, injury, or death.
Common Uses
- create a mid-rope loop that holds under a pull in one direction.
- set up a pulling point in a haul line or rope system.
- attach a carabiner, clip or rope to the middle of a line for directional loading.
- add a hand-hold loop in the middle of a rope.
- set up a Z-drag mechanical advantage system.
