Kind of a weird scenario here, but I was using my gri gri (original model) to lower some tree branches I was cutting down over the weekend. It held up fine, but some of the branches were HUGE- I would not be surprised if we're talking 1000lbs+. From what I can see on Petzl's website gri gri's aren't really tested for max load, but is there any outside testing that has been done to determine what type of load it takes to damage a gri gri?
It felt like the plastic portion of the handle was actually flexing a bit when I used it to release the cam under load, but I don't see any damage. That said, I also don't want to fatigue the cam or a hinge point or anything. At any rate it's a quite old device that saw a lot of action, so maybe it's time to retire it anyways.. just curious if anyone's ever broke a gri gri?

I've read that the grigi holds to around 9 kn = 2024 pounds of force. I've never heard of one breaking.

I've actually used a GriGri the same way. Works pretty well. But it's my "retired" GriGri. Any equipment I use for tree work or zip lines doesn't go climbing with me. Probably overly cautious, but microfractures and all that

Climbing gear is just too damn useful for other things.. I suspect there's no harm in continuing to use it, but I may retire it nonetheless. I think the only thing I'd be worried about is fatiguing the metal on whatever hinge point the cam rotates around. People still believe in micro-fractures? I'll take all those carabiners you retired after dropping

I'ts quite obvious that you don't have any idea what metal fatigue is but it's not something you need to worry about in this case. I can guarantee you that as long as the gri gri isn't physically deformed you have nothing to worry about and can continue to use it without fear.
