I’ve been using the Girth Hitch Master Point (GHMP) Anchor System for a little over a year now having learned it from the great educational social media feeds of Dale Remsberg and Cody Bradford. Recent testing on the method was conducted by Derek DeBruin and John Sohl the Petzl facility in Salt Lake City and they published these results.
“The girth hitch is a viable solution for the master point for anchor rigging, provided that;
1) Approximately 5cm of slip is within the climbing party’s risk tolerance
2) The girth hitch is cinched snugly by hand and body weight prior to use. This applies to a variety of rigging materials, such as HMPE or nylon slings or cord, as well as material conditions, whether new or used, dry or wet.” – Derek DeBruin
There’s quite a few places this system could be well applied. It is primarily a solution for multi-pitch climbing. This isn’t a great option for constructing anchors that will be used for top-rope climbing. On a multi-pitch route with bolted belay stations I might even consider keeping a sling rigged with this system (much like how I keep a pre-tied mini-quad on my harness). Even if the bolts at the next station are not exactly the same distance apart you only need to loosen the hitch a bit to properly adjust it. On a multi-pitch route with traditional gear anchors a double-length Dyneema sling is a light & fast option for rigging this system. Multi-pitch ice climbing is where I see perhaps the greatest benefit as rigging this with gloves on will often be achievable with just an alpine-draw and good ice.
Here’s a video I created showing the method along with some suggestions, namely utilizing a full strength closed rappel ring as a master point instead of a locking carabiner, which adds security and saves a locking carabiner for other uses.
Because this is a material efficient and proven redundant glove friendly system I plan on keeping it in my growing “tool kit” of options. I still carry one mini-quad with me when I prefer independent master points (more comfortable for a party of three) and use it often as a glove friendly redundant rappel extension. The advantages over tying a more traditional old school pre-equalized cordelette anchor are great enough that I see less and less reason for ever taking my cordelette off the back of my harness. I still carry it for self-rescue purposes but newer anchor methods like the GHMP and mini-quad seem to solve most anchor problems more effectively. I’m stopping by REI today to pick up one a SMC Rigging Ring which is almost half the weight of the stainless steel one I used in the video. You should consider adding this to your tool kit!
I’m running two giveaways at the moment. You can enter to win a SOL Emergency Bivvy Sack before the end of the month in the raffle at the bottom of this review of SOL survival products! You can also enter to win a camming device of your choice* by competing in an anchor building contest that ends at the end of October… rules for that contest are at this Instagram post.
See you in the mountains,
