I just learned how to lead climb and when i took the class my instructor informed us of the possibility of a gri gri not catching a lead fall. He said there is the possibility of the rope just slipping right through and not locking down, actually he said he saw it happen in the gym once and the guy decked. SO i was curious as to how often you hear of this happening?

Gri-gri's are designed for 10-11mm ropes, if you use skinnier ones - especially when the ropes are new - they can definitely slip. Dry treated ropes are even more slippery.

Also, old gri-gri's can wear down to the point where they don't catch, my old one slips on an old 11mm dynamic rope and won't hold at all on a new 10mm. It's in the Thailand pile, ropes get very fat and sticky over there and it catches fine...

When that happens it is usually the belayers fault. Often times people will grip the "lead" end of the rope (left hand for aright handed belayer) hard enough during a fall that the gri gri will not engage. However, as the full load of the fall becomes too much for the grip of the belayer, the rope rips out of the persons left hand, however enough of the force is dissapaited to the point where the gri gri will not lock.

I have had a belay grab the Gri Gri in panic when I fell and stopping it from camming and catching the rope I fell all the way down the route and through a small tree which stopped me from breaking any bones Once again not really a GRi Gri failure but more a Human error . I still use it and have been for almost 7 years now I use it for belaying leaders seconds toproping rappelling while crowbar cleaning and jugging up fixed ropes and have never had a problem its a great piece of gear. I learnt that they are not idiot proof (there is always a bigger idiot)

If you hold it upside down even with the cam up about 50% of the time it seems to not engage, kind of weird. Did a few experiments with this, check it out and make sure you know exactly how it works before using it so you know what not to do. I have only heard of problems with them on lead belay also because of the varying grip positioning.

Recently I was outdoors and a friend could not finish the top of a 10d (just burned out), so I offered to finish the top (I'd only led a 5.7 at that point, but can climb 10+ on TR) as I was not worried about a ground fall being top roped almost the entire way. My wife had me on belay, and I didn't realize she put me on a gri-gri (she's been climbing longer than I too). When I went for the final move (about 5 feet above the last draw), she didn't give any slack (harder to do with a Gri-gri), she pulled me off the wall. Instead of falling 10 feet plus rope stretch, when she braked, the rope went over the handle release of the gri-gri and kept it open. By the time she realized this and fixed it, I fell nearly 30 feet (my first lead fall, ahh!). I didn't deck, but it certainly gave me quite the scare (her too).

Lesson learned for us: we leave the gri-gri at home and only use it for indoor climbing.

If the rope ane Gri-Gri are orintated properly how can the rope go "over the handle release? My guess she is left handed or belays left handed. For right handed belayers I find the Gri-Gri safe. If left handed DON'T USE IT with the rope out over the left side.

This is a lousy lesson to learn from your wife's mistake. A gri-gri, when used by somebody who knows how to use it, is one of the safest belay devices out there, and makes up for a lot of the user error described in the posts above when used as intended. While I have both seen and been the recipient of gri-gri related errors, this has not deterred me from expanding my knowledge about using an extremely capable, effective device in its many differing, applicable situations. You should learn to use the gri-gri correctly and effectively rather than ignoring your mistakes.

Nice job of double checking each other!

In reply to:

I'm having trouble picturing how that could happen. Did she have the grigri upside down? Was it it attached to her belay loop or through her harness tie-in points?

What made you come to that conclusion? Why do you think your wife will be less likely to mis-handle her grigri indoors than out?

I tried a gri-gri on a 9.5 mm rope and it is no good. Use an ATC or other belaying devices when using smaller diameter ropes. I agree that it should be a 10.5 mm or higher. Other then the size of the rope, I've heard of nothing else except user error.

grigri's work fine as long as you

1 - use a thick enough rope .. 11mm is what i use with a grigri
2 - make sure its threaded correctly
3 - dont hold on to the cam while catching a fall ..

.. i think that summarizes it ..

.. also if you solo with it, tie a backup knot.. (that goes for any solo device) .. i liked the grigri for soloing, it was simple, and i could use it to rappel also .. it's held all 5 of my aid lead falls. (solo).

What is it about grigri threads that brings the misinformed out of the woodwork? Petzl appproves grigris down to 9.7 mm ropes. If you know how to properly use the device it will work; if you don't, use an ATC or stay home.

I cringe when I see a thread like this because they tend to follow the same structure: One poster says there was an accident with a grigri, and that the belayer did everything correctly. Most following posts blame the belayer and state that grigri cannot fail. End of story.

I think such uninformed responses end any meaningful dialogue on potential problems of grigris and everyone fails to learn from experiences of others. Well, except the original poster who learns to never ever mention it again.

Yes, many "grigri" problems are the result of poor belaying - but not all of them. Check out this url for some great information on grigris and accidents.

Sorry, but every accident cited in that article was a result of belayer error. Belay devices don't kill people--bad belayers kill people.

More of a reason to hear real life experiences and decide if this climbing tool, and that's all it is, is for you or not. Buying something blindly is never wise. Every tool we use in climbing has it's limitations.

I have a 9.8 and a 10.2 mm rope and have never had any problems with the GriGri not catching on toperope, lead, or solo. They fail because of human error. Just because you have a GriGri does not mean you can belay hands free. The belayer should always keep a hand on the ground side of the rope just like you would an ATC. If this is done and the GriGri is loaded correctly and clipped into the belay loop right side up, I dont see how it is possible for it to fail unless the belayer is a moron and holds the cam in the open position with the other hand. I'd say its pretty idiot proof. If you cant figure this out then you should probably find a different sport. Climbing requires common sense; those that dont have it are likely to get someone killed.

The only time I've ever decked while on rope was on top rope and the belayer (a beginner) was belaying with a gri gri. I got to the top of the climb and said, okay lower. The belayer pulled the lever to release me, and I started to accellerate towards the ground. Then the belayer panicked and attempted to slow me down by pulling harder on the lever. I fell faster, and went right into the ground from about 35 feet up. Now, while this was certainly my belayers fault and it happened seven years ago, I STILL don't like gri-gris.

http://www.thebmc.co.uk/safety/tech/articles/grigri.pdf

The article correctly points out two things: 1) that the grigri may not lock if the device isn't shockloaded and 2) that the belayer's thumb shouldn't be used to hold open the cam. Unfortunately, it comes to the impractical conclusion that the belayer's brake hand should remain on the rope all the time, which does not permit feeding rope out fast enough for a clip with most ropes (it will work with some new, skinny ropes). Read the directions from Petzl on how to properly hold the device to pay out rope fast for a clip.

The GriGri is a great outdoor tool, especially for belayers that aren't as heavy or strong as their leaders. The key is knowing your equipment and using proper technique. Belaying leaders with it takes a little practice, but test your gear in controlled enviornments BEFORE adding it to your rack.

A GriGri is also a really nice tool for quick belay change overs on multipitches where it's easy to set up belays off anchors.

The article makes several points. And if you chose to define them as belayer error, hey knock yourself out. One point the article does make is rarely discussed in these sorts of discussions (this thread is an exception. That is that the grigri can fail to lock if the climber does not shock the system. So if the climber eases back on the rope and the belayer doesn't know it (climber failed to say take and/or the climber is not in the belayers view), the system is not shock and the rope begins moving through the device and it doesn't lock. This can result in an unpleasant fall, sometimes to the ground. Is it belayer error that the system did not shock? Is it the climbers? Does it matter?

I think what matters is the all grigri users know that this can (though rarely) happens. That way, if it does happen, the informed belayer can take the advice in the article and throw themselves to the ground or some other maneuver to shock the system making it lock before the climber decks. This bit of information is one that is not provided by comments like "it's the belayers fault."

If assigning blame is all that matters then whatever. I personally believe it is more important to share information so that belayers know potential risks with any gear, and what to do in the event it happens.

am i the only one here that likes a dynamic belay?

occasionally i take big ol' leader falls.
i like a soft catch.

grigri's are awesome if you enjoy being short-roped and don't ever need to rapp on two ropes.

crimper: its belayer error because the dumbass took his hand off the brake side of the rope in all of those cases. had the belayer kept his hand on the brake, even if the cam didnt engage, the grigri still works like an ATC. Thus, all of those cases are belayer error, since had they been belaying properly, none of those falls would have happened.

and it is the belayers fault, because the climbers life is in the belayers hands. its his responsibility to belay properly. its obvious in every case that those belayers didnt.

the lesson to be learned is: know how to belay properly. know that, if the grigri's cam should fail to engage, you can use it like a regular ATC.....

Sorry to again assign blame, but this situation is absolutely also the belayer's fault. Once the climber begins to slide downward, all the belayer has to do is hold the brake - with minimal grip - and the device will lock.

Every Gri-gri failure that I can think of involves at least some degree of operator error, most of them substantially.

How should your dominant hand affect how you belay? The gri-gri forces you to belay with the right hand on the brake end. So if you can't deal with that, don't use the gri-gri!

The Gri-Gri has some problems as I see it, once I was top roping at the gym, it was rainning and the rope got a little wet on one end, so when my belayer started lowering me sudenly I just fell the free fall, the wet part of the rope got to the GRI GRI and it slipped, my belayer just let the GRI GRI work by itself (took off his hands from it) and I was stopped like 1 meter from the ground, quite scarry. So now when I see someone belaying with one of thos edeveces I just make sure the rope is dry.

I'll try again.

If you'd like to spend time determining who is at fault - go right ahead. I'm not arguing with you.

What I'm saying is that it is important that people understand that a grigri is not a fool-proof, always auto locking device. In those instances when it doesn't lock (wet rope; system not shocked) the belayer needs to know 1) that is can happen, and 2) what to do to make it lock. If this information is not shared, some may just foolishly assume the thing will magically lock. In that way - you are right - it is belayer error.

Is this point so difficult to get across?

crimper- no, it's not difficult, if thats what you had said initially. however, you tried to blame the device for failing instead of looking to the person operating the device.

we have the same point, you are just making it poorly.

Yes, many "grigri" problems are the result of poor belaying - but not all of them.

Where have I blamed the device?

If you are not "blaming" the device itself, please clarify what else you mean in your comment above--besides poor belaying. Thanks.

maybe you should read your posts again.

"I think what matters is the all grigri users know that this can (though rarely) happens. That way, if it does happen, the informed belayer can take the advice in the article and throw themselves to the ground or some other maneuver to shock the system making it lock before the climber decks. This bit of information is one that is not provided by comments like "it's the belayers fault." "

seriously. a good belayer will just do his job and not worry about why the cam didnt engage until his partner is on the ground or secure at anchor.

youre blaming the device for possible failures. your secondary point is that belayers should be informed so they can take the proper action when the grigri fails.

the real point is that regardless of what the grigri does, if you're belaying properly, it doesnt matter if the cam engages or not.

The safety summary tip in that pdf file was a joke. If a grigri fails to lock up (the only way I have ever heard of this happening is from failing to hold on with the brake hand) your job is to grab the rope with your brake hand. If grabbing the rope fails (highly unlikely), then throw yourself to the ground. Not with the goal of triggering the cam of the grigri, but with the goal of tangling your body up in the rope.

The title of the thread gave me the the mental image of a grigri failure taking place... springs and rivets flying off in all directions.

I have never seen a grigri failure, myself. I have, however, seen a "grigri user failure" that resulted ina 20' fall.

Most belayers should be able to lock off the grigri with the handle locked wide open. I find there is a little less friction than an ATC-type device, but still enough to lock off.

Not to contribute to this ongoing flame war but.

1. How may threads or stories do you read or hear, "My ATC failed"? The Gri Gri many be a great tool but it seems to cause problems and controversy more than any other device. And I am sure this is out of pure anger from people who hate it and not because the design of the device in some instances could be better.

2. How do you not short rope with a Gri Gri without taking your brake hand off the rope and not pushing down the cam?

No, I'm not blaming the grigri and I haven't blamed a grigri. Short of the thing blasting apart or spontaneously combusting (something I've never heard a grigri to have done) grigri's don't fail to do what they are designed to do. They are designed to lock up when the system is shocked. They do that. They are awesome devices.

Anytime a climber decks it is the belayers fault. period. (Okay, there are exceptions like when a trad leader climber place sh*t pieces and pulls them while falling. That's not the belayers fault). In general, the belayer has one responsibility and that is to keep the climber off the ground. Nothing I've written says differently.

I have just tried to express that a thread that offers nothing more than saying that it's the belayers fault doesn't offer any useful information to new grigri users and/ore climbers such as the orginal poster.

I just felt it was important to point out potential situations that can happen when using a grigri. There are many people using them, or learning to use them, or even teaching others to use them who are unaware that beyond holding the device open, or using the incorrect rope size the thing doesn't always lock up (for example instances when the climber doesn't shock the system with a fall).

Now, is such a situation happens - and it has - and the climber decks, it's the belayers fault. No question. But in some instances when the device doesn't lock (aside from the obvious belay errors) the failure to lock is not the belayers fault. (Nor is it a grigri failure). Regardless, the belayer better dang well know what the f to do in a situation like that. That is all I had hoped to express to a new climber that just took a class and asked a question about grigri and decking.

In reply to:
The article makes several points. And if you chose to define them as belayer error, hey knock yourself out. One point the article does make is rarely discussed in these sorts of discussions (this thread is an exception. That is that the grigri can fail to lock if the climber does not shock the system. So if the climber eases back on the rope and the belayer doesn't know it (climber failed to say take and/or the climber is not in the belayers view), the system is not shock and the rope begins moving through the device and it doesn't lock. This can result in an unpleasant fall, sometimes to the ground. Is it belayer error that the system did not shock? Is it the climbers? Does it matter?

Yes, it is belayer error, because if the belayer locks the rope off ATC-style, as he is supposed to, the increased frictional force will cause the cam to engage.

In reply to:
I think what matters is the all grigri users know that this can (though rarely) happens. That way, if it does happen, the informed belayer can take the advice in the article and throw themselves to the ground or some other maneuver to shock the system making it lock before the climber decks.

That's not the solution. The solution is to lock off the rope.

...had the belayer kept his hand on the brake, even if the cam didnt engage, the grigri still works like an ATC.

Not exactly. The grigri provides much less passive braking force (eg, when you thread it backward) than an ATC. However, if the belayer had locked off the rope ATC-style then the cam would have engaged.

In reply to:
How should your dominant hand affect how you belay? The gri-gri forces you to belay with the right hand on the brake end. So if you can't deal with that, don't use the gri-gri!

If a climber can't brake right-handed, he should probably find another sport, since there are the occasional belay stances which don't allow one to safely brake with his dominant hand.

Exactly. When used properly, they reliably perform under conditions in which they were designed to perform. Used outside those conditions, all bets are off.

People really either really love their Gri-Gri, or hate it. I love it and use it all the time. When used in conjunction with a brain, and the attention required ANYTIME you use ANY belay device, It is safe and effective. It's not that much different from a regular ATC when it's not engaged!

The Gri-Gri has some problems as I see it, once I was top roping at the gym, it was rainning and the rope got a little wet on one end, so when my belayer started lowering me sudenly I just fell the free fall, the wet part of the rope got to the GRI GRI and it slipped, my belayer just let the GRI GRI work by itself (took off his hands from it) and I was stopped like 1 meter from the ground, quite scarry. So now when I see someone belaying with one of thos edeveces I just make sure the rope is dry.

it rains in your gym??

Well, it's not exactly raining what I have at my gym, but it is a warm place, so it has a roof and only one wall (the one to climb) so when it rains, if it´s windy, some water can reach missplaced ropes.

i decked once becasue the belayer didnt know how to use it properly.

when i fell he gripped the lead end of the rope and this prevented the engaging of grigris mechanism. we were using 10.5mm rope and i was lucky becasue it was only about 5-6m. didnt hurt anything.

the belayer knows how to use it properly now and has my full confidence. be carefull when introducing somebody to grigri. just say to them, if i fall grip the brake end and dont panick. the problem was, whe was used to have hes left as hes brake hand, but with grigri he had to use hes right.

Both of these word are offensive; therefore, taken in that manner. I am neither. The climber never decked or even came close. The rope did not cause the device to lock.

[quote "crimpergirl"]http://www.thebmc.co.uk/safety/tech/articles/grigri.pdf[/quote]

(For some reason the bbcode tags aren't working today.

This pdf is a goner. Does anyone know anywhere else that has this file (or a similar report?). There's a guy at my gym who really likes to screw around with a grigri. Things like:

Belaying a lighter climber, holding her weight by holding onto the rope above the grigri, feeding slack out of the grigri with the other hand, jumping into the air and letting go completely (giving the poor climber a sudden jerky drop.

He's the type of guy that says 'it's a grigri, she's safe'. I've seen a few grigri 'failures' in my climbing career due to belayer error. In general, grigris do lock up on their own (hell, I use them for solo-aid), but you just never know... and why would you belay without a break hand, on any device?

So anyways... I was looking for some 3rd party research/literature on grigri failures to show this guy so he doesn't maim/kill one of the nice climber girls at the gym. For some reason my advice for him to stop screwing around doesn't phase him.

kobaz,
There is a ton in information out there regarding belay failures while using a Grigri. A forum search will get you to it. Also try a Google search.

Regarding your friend's behavior; it's bullshit and since he didn't respond to your advice, you should report it to the gym manager immediately. He is putting his girlfriend's life and body in danger AND is putting the gym at risk.

Climb safe,
Mal

I've never seen a GriGri fail. These posts got me curious as to how a GriGri (or an ATC for that matter) could fail, so I checked out the website and found a video about GriGri techniques.

If you have any questions or doubts, give it a watch:
http://www.petzl.com/en/outdoor/belay-devices/grigri

Otherwise, I'd say it's a useful and safe device so long as the belayer uses it properly.

Pretty much just the existence of the term "autolock" is the problem. Product documentation and design specifics seem unable to conquer this myth. And that shouldn't be a surprise given its locking capability has been a real behind-the-scenes driver of sport climbing since its introduction. It is inherently a functionally 'gray' device by design - locking reliably, but autolocking only incidentally. The problem is it does autolock a high enough percentage of the time that, for all practical purposes, that has become the enduring mass perception of its functionality.

And in reality, the principal use of the device, and the reason for its overwhelming popularity isn't belaying, but rather hanging, and hanging in a way that shifts responsibility for 'locking-off' from the belayer to the device. Shift that locking-off responisibility often enough and, humans being human, it should come as no surprise that most people expect the device to also initiate that locking, and therein lies the sad tale of the numerous edge cases we read about where it doesn't, thereby catching the 'belayer' by surprise. When using a grigri you have to realize that only you are responsible for intitiating locking - you're the belayer, not a belay attendant.

In some ways it's a patterned behavior/addiction from my perspective and the moral is: grigris work fine, just don't expect them to do 100% of your job even 1% of the time.

My gri gri story. I have ever once had a grigri perform...under par.
two seasons ago my wife and I found a 11b to try out for the first time. There was a walk on/off, I set up the top rope and rapped off.
While I trying to fugure out the crux move my foot sliped and fell. about 5/6 feet...
I was a bit shocked as to how I could go that far and a top rope evan with rop stretch, I like a loose bely but still.
so that night I took a close look at the grigri and noticed that its cam was really sticky and stiff. It had goten gunked up from the fine silts that are at the base the the lime stone cliffs.
I cleaned the grigri up and put a dab of cam lube on the cam. twice a season I clean the rope feeding track out and I have not yet had any troubles with it since.

If used properly Gri Gris don't fail. Neither do ATCs.

Belayers fail when they use those devices improperly. Climbers fail when they climb with incompetent belayers.

I can't think of any situation when a belay device, in proper condion and being used in the manner it was designed for, would fail. It's up to the user to educate themselves on proper technique.

[quote "mach_y"]Recently I was outdoors and a friend could not finish the top of a 10d (just burned out), so I offered to finish the top (I'd only led a 5.7 at that point, but can climb 10+ on TR) as I was not worried about a ground fall being top roped almost the entire way. My wife had me on belay, and I didn't realize she put me on a gri-gri (she's been climbing longer than I too). When I went for the final move (about 5 feet above the last draw), she didn't give any slack (harder to do with a Gri-gri), she pulled me off the wall. Instead of falling 10 feet plus rope stretch, when she braked, the rope went over the handle release of the gri-gri and kept it open. By the time she realized this and fixed it, I fell nearly 30 feet (my first lead fall, ahh!). I didn't deck, but it certainly gave me quite the scare (her too).

Lesson learned for us: we leave the gri-gri at home and only use it for indoor climbing.[/quote]

Your wife lied about what happened. What you described borders on the impossible. The much more likely scenario is she screwed up somehow, most likely by clamping down on the device with her hand in a moment of panic and kept it from locking up. She was afraid to tell you the truth, or possibly in the way that only women can, convinced herself whatever happened wasn't her fault and made up that scenario in her head.

1) cheesetits
2) zombie thread hungers for BRAINS!
3) the scenario described is possible, provided the belayer has no idea what they are doing with a gri-gri for a leader. The gri-gri has a designated chirality to it, and trying to use the wrong hand for the designated brake hand can and will interfere with the safe operation of the device
4) holy implied misogyny batman!

Yes, it is like when people driving refuse to use their turn signals because they do not want to lose the element of surprise!

All you need to understand is that we're crazy.

Once you learn to accept that, life will be a lot easier.

I hate that. Driving is not like boxing, telegraphing your next move will help *prevent* getting your clock cleaned.

Other pet peeve: turning your turn signal *after* you've committed to the turn. [sarcasm]Oh, you're turning! I thought you just cut across three lanes of traffic because the relentless ennui of urban life had finally driven you over the edge.[/sarcasm]

Or how about the douche bag who comes up behind you, just sticks up your ass for a couple of seconds, swings out, guns it hard to get around you, pull in front of you and hits the brakes because *NOW* he needs to turn right.

I resemble that comment. Perhaps he learned to drive at the same school as me ... i.e Sears Point Raceway.

With all the idiocy surrounding the GriGri it might be time we throw the GriGri out and start having people belay with the I'D S. That belay device is pretty fullproof. If you thread the rope backwards it will lock. If you crank on the handle, the handle will disengage. If you need to take your hands off the rope, you can switch to the lock mode and the cam will pinch the rope and completely prevent it from moving in any direction. You can also do 250m raps with it and lower 150kg loads by yourself. It is like a GriGri on steroids. Maybe the next time I have to take a noob belay lead test at some random gym I will use this guy just to piss them off. Oh wait, if one cannot figure out a GriGri then...

Please don't mind friends, try to study why this happening? but as I knew everybody must know limitations of equipments. It'll will mention on Manual.
