'Essential Knots: The Girth Hitch' is part of the book - Sport Climbing Basics.
The girth hitch (Larksfoot) is used for:
- Attaching slings to your belay loop
- Attaching slings together
Feed a sling through your belay loop.
Put one end of the sling through the other.
Pull it tight.
You can also link two slings together using these same steps. Arrange the girth hitch as shown to create a strop bend. This is basically a neater version of the girth hitch.
