Adjustable grip hitch
Type of friction hitch
The adjustable grip hitch is a simple and useful friction hitch which may easily be shifted up and down the rope while slack. It will hold fast when loaded, but slip when shock loaded until tension is relieved enough for it to again hold fast. It serves the same purpose as the taut-line hitch, e.g. tensioning a tent's guy line.
This knot is also called the adjustable loop[1] and Cawley adjustable hitch. It was conceived 1982 by Canadian climber Robert Chisnall.[2]
