Figure 9 Loop
How to tie a Figure 9 Loop Knot. The Figure Nine Loop, sometimes called the Figure of Nine is used to form a fixed loop at the end of a rope. It is tied in a similar fashion to the Figure Eight but with an extra half turn as the last step before finishing the knot.
While it makes for a bulkier knot than the Figure Eight, it is considered to be stronger and also easier to untie after heavy loading. Due its bulk, it is more suitable to be used in smaller diameter rope and is particularly unsuitable with heavy stiff rope. Known to be a popular knot choice among cavers it is also a good knot to put a loop in webbing material.
