The Scaffold Knot is a sturdy loop that slides to fit snugly around a bar, rail or other object.
To Tie a Scaffold Knot:
| Form a loop in the working end of the line, then bring the working end around the back of the standing part. |  |
| Bring the working end back across the top of the loop. |  |
| Bring the working end around the back of the standing part a second time, like shown in the photo. |  |
| Take the working end up through both loops and tighten by pulling on the working end and the loop. Be sure the turns around the line lay down neatly against each other. |  |
