Dropped GriGri 2

So as the title says, I had a friend that dropped their GriGri 2 from roughly 20ish ft and fell on hard packed dirt/rock. It was literally brand new and they inspected it to check for damage. Looked ok but I have heard numerous statements regarding throwing away biners and the like when dropped.

Can anyone weigh in on this?

thanks

Does it still work?

It's dangerous, you shouldn't use it anymore. But it's also a hazardous material, so don't throw it in the trash. Ship it to me and I can dispose of it properly. I'll cover shipping charges because I care about the environment.

Almost as novel as the original post.

Yes, still works.

Is there any major damage that, in your opinion, would compromise the integrity of its operation?

It's fine. Give it a visual inspection for any damage beyond a scratch if there isn't any you're good to go.

Personal comfort really. The most conservatives would say "retire, is your life worth $90?"

Others will sling their grigri as pro in a crack, take a whipper on it, unmangle it and call it good to go.

If it was mine, I'd give it a good look over, make sure everything feels normal, and if so, keep using it.

But the micro fractures.... Oh the micro fractures....

from fall protection training class, "if you don't know, it don't go". perhaps you should be asking petzl what they can do for you.

I use a GriGri 1 as the rope-end tether on our pull tester and it´s been in the vice and hammmered open when it´s jammed, bent completely open and beaten straight again with a hammer and survived (barely) 18kN pull before the rope broke, at the weekends it´s my rope-soloing device. Marc Beverly (if I remember right) also used one as the rope-end tether when he was destroying belay devices doing drop tests, they are amazingly robust.
On the other hand Americans are rich, the dollar strong and the French economy needs all the help it can get so please buy a new one.

The last time I dropped something--an atc--it was from about 80 feet, and I threw it away immediately--without question. Interesting topic...

At 20-ish feet, the impact speed is in the 15-25 mph range.
At 80, it's more like 50 mph.

Either way, I am thinking about my gear as if it were hit by a car. I'd throw it away. Or mail it to Nathanael.

Wait, Jim, what kind of rope survives all the way up to 18kn in a grigri? I thought most dynamic ropes and even static taglines are only rated around 8-9kn.

That's because the UIAA number for dynamic ropes around 8-9kN is not the absolute tensile strength, but rather the impact force that results from a factor 2 fall in a standard UIAA test. The max strength is a fair bit higher (they don't publish that number).

On a separate note I just clicked on your profile bmd and recognized the picture from you at the beach. We swapped stories around the fire at New Jack City on your first day back at climbing after your accident.

Belaying with it is fine - just don't rappel with it.

Good to know! Too bad my body is probably not going to respond too well to 4000lbs of force, but at least the rope (and "microfractured" grigri) will survive.

Yay small world! I'm lead climbing again now!
Here's a video of that night at newjack:

your life is worth more than $90. get a new one and send your old one to me because i need a grigri for a use that will in no way ever involve climbing. or maybe i'm lying and will use it for climbing. dealer's choice i supose

I was also at new jack that night and remember that crazy story. small world.

BD QC lab

and yet there has not been a documented case of a modern climbing rope in good visual and tactile condition that broke which wasnt cut or due to chemicals ...

as to yr grigri ... if all the functions work fine and theres no visual damage ... send it to me

;)
