PRO Tip: How to tie a Scaffold Knot

In this instructional video, CMC School Instructor Doug McElmury demonstrates step-by-step how to tie a scaffold knot. The scaffold knot is often used when a compact knot is needed that pulls tight and grips an object. Examples of use would be connecting an end of a mechanical advantage system (MA) to the becket on a pulley or an escape line to a carabiner/hook. It is a great knot to incorporate when you need an MA to be as compact as possible on a vertical raise with a high anchor point such as an Arizona Vortex or tripod in a confined space rescue.

The scaffold knot is similar to the poachers knot, and can be interchangeable in the operations mentioned above. However, in some cases, a scaffold knot will provide an additional eight or more inches of travel in an MA by eliminating a carabiner and replacing a Figure 8 on a bight.
