Structure

Tied in the bight, the Figure-of-Nine Loop is made similarly to a Figure-of-Eight Loop but with an extra half-turn before finishing the knot.

Strength/Reliability

While it uses more rope and is bulkier than the Figure-of-Eight Loop, the Figure-of-Nine Loop is somewhat stronger and less likely to jam after heavy or prolonged loading.
