I To join two slings when strength is a concern, use a carabiner—not a Girth Hitch. I've recently started making my alpine (or "trad") draws by girth hitching one end of a sling to the gear side carabiner and then The specific method taught was to girth hitch one end of the sling into my tie-in loops and then to girth hitch the other end to a biner which is then clipped into the anchor. If the other anchor Same principle applies to a girth hitch anchor, here are made with Dyneema. #amgatechtuesday. There is debate among climbers as to how significant is this reduction in strength, and whether the alternatives, such as joining two slings with a carabiner, are indeed much better. to a krab) Here's an unconventional approach to anchor building - tie a girth hitch at the master point. This was tested by our friends at HowNot2. Called by the name alpine girth hitch by climbers who use it to eliminate the need of an extra locking carabiner, it doesn’t create any excess stress on the tying rope but reduces Let's address that “how strong is it / doesn't a girth hitch weaken the sling?” a question right off the bat. I’ve been reading Anchor blowout with a South Tyrolean belay in which the double-strand section of the sling bears the load. This technique has spread throughout the United States in Also be sure to only hitch to stable trees, rocks, etc. Here we It shows 2x the kN load with a basket hitch, around a 30% reduction in load capacity with a girth hitch around an edge-less "Girth Hitch" you'll find some real data from Chris Harmston at the Black Diamond labs, albeit tests on single samples. Conclusion (published The disadvantages of using a girth hitch as an anchor are several: the strength of the webbing is reduced by a large degree, they increase tree trunk damage due to the narrow contact points Stated strength for a girth hitch varies from one report to another and with the specific connection (around a large object, sling on sling, on a carabiner), knot orientation (bend angle), and sling Strength: The Girth Hitch weakens a sling, particularly if two straps are directly knotted to each other. But are you sure it was a 50% strength reduction for a girth hitch as being discussed here (i. Two spectra slings girth hitched together failed Anchor blowout with a South Tyrolean belay in which the double-strand section of the sling bears the load. g. Uses: The Girth Hitch attaches a sling or a webbing strap loop to your harness or to Take the cow or Stilson hitch, essentially a girth hitch with a half hitch. Make it your standard practice for the leader to place a first piece (aka "jesus piece") prior to leaving the belay so that any potential fall right off the belay hits the piece first Essentially, a knot reduces the strength of textile materials due to the imbalanced distribution of the load on the fibers. Is this a troll? You mentioned potential energy: Assuming a 60cm sling folded in In reply to Petegunn: All knots/hitches weaken slings to some extent. as the hitch's strength will rely on it. The knot's bend radius is a key factor and is Researcher and AMGA Certified Rock Guide Derek DeBruin partnered with Petzl USA to perform a rigorous analysis of the girth hitch master point. This loss of strength is worse, e. The half hitch keeps the knot stable and allows for When using a girth hitch, minimize sharp bends in the material and strive for setups like the right hand photo to maintain strength and reduce wear. Next time you hear somebody saying “OMG, don't use a I think the girth hitch might be particularly bad because it has mechanical advantage where it makes a collar around itself, where it is basically trying to cut itself in half. If the other anchor Abstract This study explored characteristics of the girth hitch as a tool for rigging the masterpoint of recreational climbing anchors. This has two main advantages over the What percentage of the ropes strength is lost when you girth hitch it to a carabiner or ring? How does that compare to connecting directly to a spliced end of the same Through a comparison of the break characteristics, Mammut believes that the broken sling in question was cut by a sharp object, rather than breaking under load due to the weakening Unlock the art of tying a perfect Girth Hitch Knot: Simplicity at Its Strongest with KNOTMASTR! This knot may look simple, but its strength is unbeatable. Dynamic test in Yann Camus' video: slipping of the girth hitch showed a force reduction. com. , close to 50%, when tied in the form used in the A description of how to tie a Girth Hitch for rock climbing, and a list of applications for the Girth Hitch. On trees, line up the outer loop with the The Girth Hitch is an easy way to connect a loop of webbing or cord to a fixed point like a tree, or your harness’s tie-in points. e. Pass one end of the loop through the other end, and cinch tight.
