Should've named the video: "The grim reaper hates this one easy grigri trick" ...but then maybe your weird cousin would be back and UA-cam wouldn't approve 😅
Theres also a big issue with being too close to a low anchor, in a top belay situation. If you contact the anchor when the climber falls the grigri can flip upside down and it completely unloads. If your hand isnt on the break linr then the climber that just fell pulling you into the anchor is now free falling even further. Its happened to me on both ends. luckily both times, hands were on the brake line and it only ended up in a panicked 5 ft drop.
This also applies when you're belaying. It's easy to deck your climber if you have most of the rope out and your climber is near the ground. If you don't have your hand on the rope and you release the brake as we've all seen here, that rope whips through the grigri due to the stretch and before you know it your climber is on the deck. Every grigri accident I've heard of is on the belay and this shows one example of what can happen.
That wouldn't happen if you were tied into the belay loop which you should be. That could only happen if you only had the rope in the grigri, and grigri attached to belay loop and the rope end wasn't. That's not the way you set it up dude that's dangerous. He's not talking about that, he's talking about rapel.
Ah OK sorry I read it again and I think you mean you have slack, but are tied on. Yes I could see that happening but I guess it shouldn't if the belay is paying attention.
I've seen a climber dropped with a GriGri1 device, and wonder if the anti-panic in the GriGri+ solves this. Does it stop you releasing the brake enough? I guess the rope stretch is there with the old style tube or bug device, but with the tube device we're always holding onto the brake line for dear life because if we let go the climber will just fall.
Haven't climbed yet but have been really wanting to get involved. This is such an important point to make and something I never would have thought us. Thank you for making this.
Mabye I got some things wrong at first place or a different approach to decending on rope but I have got some questions: Why are you decending on a single rope? How do you get your rope back? And adding a Prusik-knot or something similar at the unloaded rope solves the problem you are pointing out. In my opinion this should be standard anyways. Please correct me, if missed the point.
Start watching at 6:00. Problem is when you're setting up an anchor on top of a rock climbing route, it takes sole serious math work to tie the end knot at the exact right spot.
Hmmm... Interesting. I would have never thought about that! Generally, I instruct by saying reason for the brake hand on a GriGri is just in case maybe the device fails or installing the rope was backwards, essentially turning it into an ATC.
I always assumed it was to prevent the brake side of the rope from somehow finding itself in a feeding position (upward out of the grigri), preventing the grigri from breaking properly.
@@melkorWTF Ya. Kind of strange. Reason why you always got a stopper knot in the end. If you rappell as much as I do, typically you're not looking for the end of the rope as would assume that you'd run into the knot instead.
@@trip7shark Haha I mean the guy with a red shirt that literally falls from a tree rig demonstrating the camming action on the grigri failing to initiate
I would never rappel on a grigri type device, but never say never... Let's imagine I'm forced to, It would have surprised me for sure. I honestly did not know about that hazard, so it's a real thank you I guess. I usually never let go of the break side of the rope but here again, never say never, that's why it's called an accident after all. Great video as always.
the rope stretches 30% under super heavy loads, as in it might hit ~20% with a heavy whipper. The real test you're doing at 8:00 is a static stretch, which will be much lower, around 10%
Long rappels, Petzl recommends using an extra, small sized, braking biner, or attaching the grigri with one that has the brake built in like the Petzl Freino (personally, I've never seen braking biners used except underground/caving)
I experienced this today, i never let go of the brake rope, but i did a 60m dynamic rope rappel and the rope was just trying to fly through my atc because of the elasticity. Luckily i had a third hand. Not to mention the atc felt like it was hot enough to melt my rope if i stood in one spot.
Wouldn’t it act different with MORE weight on the line (holding the cam locked tighter)? It would have been cool to see it done with a 50m rope as that’s a length I’m likely to experience.
When you pull back the lever (unlock the cam) it releases the load because the rope has the weight off of it and flows through the gri gri with no traction. The point being is that the hazard is when the cam is unlocked. Essentially the weight is off of the cam at that point. More weight would mean more rope stretch, meaning that there is a greater potential for more rope to be pulled back through the device once the rope is unweighted (cam unlocked).
@@BetaClimbers oh yes, you did make that clear in the video, I just like the idea of a silly video using 2 gri-gri's. Also keen to see that biner video. (Already subbed with notifications, too good a channel to miss a video!)
@@magwitch right on appreciate it 🤙🏻 yeah that would be a funny thing to see lol I can imagine some one trying to set it up as a top rope solo back up if they didn’t know what they where doing. Lol 😂
There are lots more things that contribute to extra distance for a leader fall. Slack in rope + stretch in rope + slack in belay + stretch in belay + slack in pro + stretch in pro - rope belayer can haul in. What you estimate is a 2m fall can easily become over 10m.
This is such an important video maybe you should trim the start a bit or add another few tips at the end if you want to achieve a certain length. Thanks for making this.
I am a cave climber. I use a semi static rope. So it still has some stretch. Once I rappelled down the full 50 meters of my rope. Got out of the rope at the bottom close to the end knot and siiiiing: looked at the rope dangling 3 meters over my head from the middle of the cave ceiling. (I survived, because we used two ropes this day and I stopped the other guy from untying his rope.)
Yes on a Quarry vid! And where's your video on your Dad's route? Informative and entertaining content as usual. And I was one of those nubs that tried to uncoil their first rope from the floor, most frustrating 30minutes of my life. :)
I have that very same rope. Mammut Classic 9.9 80M We call it the "Long Running Bastard." Heavy as hell, management nightmare at an upper belay station BUT you will NEVER run out of rope on any pitch. Rappelling on a Big 8, that rope feels like it goes from 9.9MM to an 8 real quick towards the end!
Using both the Sender harness and a We Care 80m. Been a tremendous fan of both, though will say would’ve appreciated the front loops were not coated but the same low profile nylon as the back, as well as only Edelrids are properly lap coiled, but Mammut is the best of everyone else.

I dont rapell on grigris. I use em soley for lead belay, folowers get belayed by me with atc guide from the top and to rapell i use the atc aswell or the 8 if the atc is not available. Ive also never done long single rope rapells. Only one single one wich was like 12m to clean and check out a possible bolder /short route in my area. Wich i ended up first ascending on toprope since there is no cracks or anything and i didnt want to bolt virgin rock with questionable legality.
It makes sense to me. But I had never thought about that. I don't think I have ever rappelled on a single strand dynamic rope, only static, or double rope. But I guess it could happen with double ropes as well with a brake like mega jul.
@@JulioNavarrete-u4q that’s very similar to the birdie and also very grigri like (just smaller) I’ll think about doing a review of them but it would act the same as a grigri would. 👍🏻
Letting go while pulling on the bar is ridiculous, never seen anyone do that.. seen plenty of people briefly let go when system is statically weighted though
It’s not so much about pulling the bar and letting go. If the rope has enough plastic deformation, there can be a tremendous amount of pull back. Even with a hand on the break a large amount of rope can snap through a grigri. If you rappel while “Riding the pig” or in a rescue attempt you will feel it for yourself especially if you try to unweighted the rope abit while near the end of the line. So it’s best to ad some friction to help counter act that. I made a short video on one way to do that quickly.
@@coachingtips9686 oh I am artificially adding body weight and stretching the line by pulling back with my legs then pulling on the grigri handle. The rope snaps through the device when I pull on the handle. Pulling on the grigri handle releases friction on the rope.
The most logical way to understand why you should always hold the rope is that if it was safe not holding it than manufacturers would say that. Because it is advantage. Who wants to hold it for no reason? So if thay said to hold, that means it is the only safe way to use this belay device.
That problem with that is if you don’t give people a good reason they may go one thinking they know more then the manufacturer and that the manufacturer may just be covering there ass with over safety regulations.
It doesn't need to completely open to let the rope sing through. If you imagine how a springy rope can lead to a jerky rappel, eventually each jerk becomes a huge amount of rope popping through the device.
If your belaying and you use that much rope, you need longer ropes or shorter climbs . You should never be that close to the end. Stopper knots are for not only for safety, but it's an excuse by some climbers to pay out to much rope. Change your belay station or climb something shorter...
Reason #1237 to always knot the ends. But i'm not convinced about the springing action. Wouldn't rope stretch happen gradually over the length of the rappel, so at the end only the 10' tail would have stretch left? Does anyone have a link to a report or an anecdote where this springing action was the primary cause of the accident?
It's a loaded spring... Josh is the weight dangling. When spring is suddenly released, the climber decends, but the rope accelerates up at the same time and could whip through the device quickly. In Scotland we use prussik loops...and a knot on the end. This is an epic video and reminds us why!
The bulldozer is rated at 21kN, for those who were wondering
So many experienced climbers died because of the missing end knot... It's a shame...
Good Grigri Hack 👍
this is all new to me, but i will say, that end of the rope was on my mind, i said, self, i wonder if there should be a knot on the end, oh yes,

It doesn't need to completely open to let the rope sing through. If you imagine how a springy rope can lead to a jerky rappel, eventually each jerk becomes a huge amount of rope popping through the device.
Grogris are shit for rappelling on since the cam opens up too quickly. You effectively showed that with your spring issue. Use an ATC or other device.
