One of the things I love about climbing is how we keep finding better ways of doing things. Sure, we get into ruts where we resist trying something different (why fix it if it ain’t broke mindset), but every 5-10 years I notice we make another leap forward because someone decided to think outside the box and try something new.
Most people who climb with me know I have an affinity for the “mini-Quad” when constructing my anchors. If you are not familiar with the “mini-Quad” check out my post and video about it here. The mini-Quad is still my “go to” choice when climbing in a party of three or more (mostly multi-pitch guiding), simply because having two separate master points is more comfortable for guests and helps with keeping things organized.
If I am climbing in a more common party of two though, I’m going to be using the Girth Hitch Carabiner Master Point a lot more frequently. It has some great advantages to other methods like;
- Does not require long sling/cord material. For a typical two point anchor (bolts) a single shoulder length (60 cm) sling is sufficient.
- It’s super fast to tie. Try it two or three times and you’ll see how fast you can build this.
- It’s super fast to break-down. Since it is a “hitch” and not a hard “knot” once you remove the carabiner it vanishes. No welded dyneema knot to work on!
- It’s redundant. Testing shows if one leg fails or gets cut (rockfall) the hitch will not slip! Compare this to a “sliding-x” anchor with the same length sling and this is definitely better if direction of load is close to uni-directional.
- It’s “equalized” to the limitations of the physics. Yes true “equalization” isn’t quite possible but close enough.
- It has zero extension should a leg fail.
All of this adds up to a great SERENE, RENE, ERNEST, NERDSS or whatever acronym you like when debating or evaluating the merits or flaws of an anchor.
- It requires an extra locking carabiner to form a master point.
- It is a “pre-equalized” method, meaning of the load direction changes you’ll lose load distribution (just like a tied off bight).
- Every one is attaching to the same master-point, so for party’s of 3 I might more often opt for the mini-Quad
I plan on using one of my Black Diamond RockLock Magnetron carabiners as the master point carabiner for a couple reasons. It’s a fast carabiner to deploy and it auto-locks, but I prefer the added security of the style of locking mechanism since I am clove hitching myself into a separate locker attached to this master point locker, and will be belaying off a plaquette as well. While it should go without saying care needs to be taken when introducing this method, especially to newer climbers. Since the master point is a carabiner it is crucial no one mistakes this carabiner as their own attachment and removes it when perhaps taking the next lead. This perhaps is even more reason to use a Magnetron as the master carabiner and screw gate carabiners for your personal tether/clove hitch with rope attachments.
Regardless of what locker you use as the master point I would recommend having your belay plaquette set along the spine of the carabiner vs your own tether attachment for maximum strength and security.
Vs. The Clove Hitch Master Point Carabiner Method
Another similar looking method uses a clove hitch instead of a girth hitch to achieve many of the same advantages, however I find the girth hitch slightly faster and easier to tie.
The Girth Hitch Master Point Carabiner is a slick new solution to add to your repertoire. It is not a “solve-all” solution but based on context I can see this option being used efficiently and effectively in many situations. As with any new anchor skill practice on the ground first before you use it 100 feet off the deck. Seek proper instruction from qualified guides and instructors.
See you in the mountains,

Very good and informative post David.
Every now and then, I also use such method for fixing my master point and as you have already perfectly said, there advantages and some disadvantages.
Thanks for sharing your thoughts on the matter.

Hi! Thanks for a nice article. Do you have any links or info on how this has been tested? I read about it having been tested, but have never actualy seen anything beyond what people do at home. A real FF2 test with one piece coming out would be the gold standard. Cheers! john
Hi John… my friends over at Alpine Savvy have linked a bunch of videos, some of which include some decent testing. You can check it out at the link below. I’m not too concerned with it failing with a FF2 as that should never be an force any anchor sees… ever! https://www.alpinesavvy.com/blog/try-a-girth-hitch-at-the-master-point
Thoughts on using a figure 8 as a masterpoint for this anchor? Just bought a BD Super 8 on a whim, my plan was to girth the smaller loop of the figure 8, leaving the larger loop open for a nice clean masterpoint that I wouldn’t have to worry about locking/unlocking.
