Scaffold knot

The scaffold knot forms a string sliding loop that can be place around a metal eye or some other

fixed point. It is a triple overhand noose, named for its likeness to a hangman’s knot.

Start with a large loop going through the eye (1). Bring the working end around the whole loop
several times (2), working toward the eye. Then feed it through the wraps alongside the standing
part (3). Pull the standing line and the working end to tighten (4). Snug the knot up against the eye

to finish (5).
