Introducing the "Agile Friction Hitch", a novel Friction Hitch, also referred to as the "Agile Hitch". Similar to the Prussik, Klemheist, Autoblock, Hedden and Bachman friction hitches, all of which are tied with a loop (Prusik Loop), the Agile Hitch is also tied with a loop, but is easier to break under load and easier to advance in climbing. When used in rope climbing applications (similar to the JRB Ascender Hitch), it can be used as a substitute for a mechanical ascender or primary friction device. The hitch incorporates the optional (but recommended) use of a carabiner as a handle. The carabiner receives no load except that which can be exerted by the force of one hand, and as such, the type and size of the carabiner can be less substantial than one used in life support.

Thanks. I am just trying to be thorough and anticipate questions. It's much easier and pleasant for me to respond to this type of comment than one with a question that was caused by my lack of detail or presentation.

@@jrbtc I just had a funny vision. What would be funny is if you were to make a tier list of hitches/bends/loops in the style of a “Tier Zoo” tier list. These style of videos are often comedic 😄 MedLife Crisis put out a hilarious organ tier list… Random thought, I know… But, you have a lot of knowledge on this subject so it would be interesting to see your appraisal of the various knots from each category 😆… Prusik (A Tier), Bowline (S Tier), Hangman’s noose (F Tier 👎), Square Knot (C Tier) …. 😂 just a thought

amazing what the extra wrap (somewhat) at the bottom of the hitch, (making it a variation, of the Klemheist as you say, ) will add to the utility of this hitch, would be a great hitch to throw on in case of the need to bypass a limb when you don’t have an extra set of hitches on the rope, so easy and quick to tie! thank you JRB , another tool in the toolbox!

the agile hitch is awesome, used it as a backup on srt pole hitch climb above the jrb compact 5-2 -3, grabs and releases really good, and really adds to my peace of mind for redundant safety both on ascent and rappel ,thanks John, threw it on because my 5-2-3 was slipping a little freaking me out , but it just needed tuning

I forsee this pairing perfectly with the jrb cinch! It will also be very handy if someone wants to sit in a crotch that's "tight." I had a few instances where I couldn't pass the rope over with the jrb acsender hitch attached. This will solve that problem! Pass the rope over naked and then slap on this Agile friction hitch!

@jrbtc Жыл бұрын

Excellent point. This is EXACTLY one of the problem scenarios it mitigates. I also have a false crotch rigging scenario which needs a bare rope as well and the ability to easily removed and replace a hitch enables us.

hi John, I go with JRB ascender hitch, in SRT rope system, easy and safe no jamming, I use 6mm aramid core, thanks for video and wish you as always a good day.. regards.. 😁

I like your choices. And for anyone reading the comment, although some of the advanced fibers are heat tolerant and some are not, and we prefer heat tolerance, as long as we are managing slack and using something else to absorb friction on rappel ( such as munter or figure 8), we can execute an efficient climb on a wide variety of materials.

Can’t wait to try this out. I like easy but it looks good in every other way that I can think of. Thanks

@jrbtc Жыл бұрын

Thx Jeff. The handle is a big enabler, not only as a handle, but it keeps the hitch in a uniform and moveable state.

Hi John.. I find you extremely thorough in your teachings. You have inspired me to climb on your system and it works well. Love your videos . With that being said, you might advise new climbers who may also be insired by you to carry only climb rated carbiners, and thus eliminate the possibility of them grabbing the non rated carabiner (intended for the handle) and using it for life support. Thank you for your attention to detail

@jrbtc Жыл бұрын

Thx for the comments. Will note that point in future demonstrations. For me personally, all miniature carabiners that I might carry are not used for life safety applications, even if they might be rated for such. Any full size carabiners are rated. Even if I am blindfolded, I can't make a mistake.

Very interested in this hitch. Looking forward to incorporating it into my climbing system for doing bypasses and also sending the rope up through a tree crotch bare. Great work.

@ongridself-reliantfamily1751 Жыл бұрын

Very cool hitch. It feels a bit like the Catalyst hitch with the cross over around the back, and then pass through. I am using a Catalyst hitch on my work positioning lanyard, and I really like it. I am going to try out this Agile hitch, and see how it feels. I really like what I am seeing here. Especially that it is easy to tie on the fly. Just a thought, you could probably tie it with an eye to eye cord. Just clip a carabiner through both eyes after passing both through the loop at the end. Finding a eye to eye cord that long might be a bit of a trick though. Thanks for the interesting knot to explore.

Very interesting, looks like a great ascender hitch. I’ll have to look closer into this and test to see the advantages, over the JRB ascender hitch as that’s the only primary hitch I use. Do you see this taking preference over your JRB ascender hitch in your own climbing method? Specifically in your JRB climbing system using a stationary double rope method?

@jrbtc Жыл бұрын

I have done side by side tests with an Agile Hitch on one side and a JRBAH on the other side of a doubled stationary rope system. In ascent, they behaved identically. The JRBAH is a bit easier to break in order to initiate rappel. And so, i feel either can be used. I prefer JRBAH for SINGLE ROPE climbing. However, in my quest for a Universal system which can be used for doubled stationary rope climbing AND JRB Hitch Climbing... the dilemma is that the hitches go in different Places and work in opposite directions. And so if we use Agile hitches for the former, It's not much of a problem if we want to occasionally pop off the Agile Hitches. We don't actually NEED to remove them, but we may not want them on the rope flopping around and so we CAN if we want to.

John so currently I am using primarily a double michocan for ascent and rappel. Im climbing on a single rope system while one sticking. How would you compare the agile hitch to the double meech?

@jrbtc Жыл бұрын

In a one stick application, I need a hitch that automatically tends. DM will do so with no metal but I prefer a compact JRBAH. And yes, we could use the Agile Hitch but with the Buffalo Hitch to get the tending feature. I would tie and test to see if you're comfortable with the force necessary to break it. And consider that if you gave it a little shock load for example after a stick kicked out and you fell a few inches, it might be set a little harder. We have to be prepared to get out of that situation as per my dedicated video on that topic.

Using a half rope raises concerns about potential failures, such as if one rope completely fails above you or if a friction hitch fails to grip. Specifically, when rigging the rope just over a branch, does this pose a risk of falling? Therefore, does Double Strand Rope Technique (DSRT) lack an advantage over Single Rope Technique (SRT) in this scenario? In this case, does using two strands in DSRT not increase redundancy compared to using one rope? Can only one side in DSRT hold when the rope is rigged just over a tree branch? Additionally, is it possible that in the event of a failure of one friction hitch, the rope holds due to the footloop and the garda hitch? ....Please read between the lines because of my english knowledge is it possible that to your ears something sounds weird or a little incorrect. I hope you understand what i want to say. Thanks John

@jrbtc 7 ай бұрын

If we use the same rope and the same friction hitch in a DSRT system vs an SRT system, rigged in the same tree and crotch, the advantage in strength goes to DSRT because we have half the load on each hitch and rope segment. In both cases, if the Garda hitch is engaged with the "best friend " connection to the lower bridge, a failure or slippage of the friction hitch is mitigated. We will not fall. But need to repair and recover. See my video on self recovery on the DSRT playlist.

Hello john! I've recently purchased 300' of ⅜ static rope for an emergency rappel situation for my family if we are ever in a burning building up to about the 25th floor I figure so 99٪ of the hotels we'll be staying @. Since I'm the only slightly experienced technician in the team based rescue world, not lead climbing, I have two main options/questions what to use considering my inexperienced wife & 3 kids could be using this system as a last resort emergency escape system: do I employ the mùnter on a carabiner vs the rescue 8 as my friction hitch & what should I use as my backup hitch incase it gets weighted I'm afraid the prusick will become permanent & they will be stuck there & anyone coming down after them will be also. It's this nightmare scenario that I've considered not having a backup hitch to avoid getting stuck and blocking our egress when we only have 1 rope.

@jrbtc Жыл бұрын

This is a serious topic and not one I feel qualified to comment on in any detail. Even for an experienced climber, there are different factors in play at that kind of height. For example, the way I typically use a munter, i am holding the rope out and away from me to neutralize spin. Ok, well if i am 250ft up, i have to hold up 10x more rope. I might get tired and let the rope spin... which could get the rope in a state where i get stuck. Consider that each person needs their own device and friction hitch if you are using one. This hitch is easier to break than the prussik, but not as easy as the JRBAscender, but I can't say that either are right for this application. Pls consider consulting with a Rescue. professional.

@imaphxaznative Жыл бұрын

@JRB Tree Climbing and Saddle Hunting john you bring up a good point about having to lift 250+ ft of rope getting heavy for an adult & probably impossible for my 7 yo daughter, that being said the mùnter is probably out in favor of the figure 8 or rescue 8 which pulls down to achieve greater friction vs up like the mùnter. The other question of which/ whether to include a backup that could stop their progress. Sounds like the jrb ascender is the easiest to release for a child or an adult. My wife is slightly heavier than average so although I hope to never need to deploy this system I want their best chance of survival if it is.

You're gonna melt your prusik....

@jrbtc Жыл бұрын

There is no Prusik here. I realize you are referring to the CORD that we are tying the Agile hitch with, but it's incorrect to refer to anything in this demonstration as a prusik. Melting the cord could only happen if we subject it to an inappropriate amount of friction, for example using it as a rappel device. We don't use a friction hitch as a rappel device in a single rope system. It's only a backup in Rappel, nice and loose, as demonstated. The friction on rappel is supplied by the munter, or Figure 8 or whatever we are using. The hitch is in my hand and only gets slightly warm during rappel if used properly. Of course, there are Heat Resistant Cords available for friction hitches, but they aren't necessary if the hitch is used as demonstrated.
