USnavy's senario will not work unless the biners are loaded ove an edge in which case lockers will also break. in a straight direction of pull the rope always breaks at a knott even with retired non locking biners in the system.

Apologies to all for digging up a done and dusted thread, but I have a lot of catching up to do (being a complete noob)
Thanks to various thread on these forums I became aware of the story relating to Lynn Hill, I know all of the people here already know the story, and being a complete noob I do not have the qualifications, expereince, skill or knowledge to dare point out that the tragic accounts of accidents or misjudgements of expereinced climbers happen far too often.
But the fact is the simplest of noob errors are not restricted purely to noobs. I would like to thank cracklover for the demonstration of how this might occur, it has certainly reinforced in me a drive to not become complacent in my new found passion for rock climbing.

How about giving double the money for locking biners ?
It takes a bit of fiddling, but set up 2 opposed locking biners in a top rope situation. Rotate one of the biners, so they are still opposed but gates are on the same side. Now push one through the other till it jams, with the rope passing over the locked gate. The rope can be shredded ! It has actually happened.

possible both gates open weaken binner 'gate slap'In reply to: , anybody think about setting up anchor on multi pitch what if the anchor is the top rope....failure of the system could happen, not sure which part would fail first, they have books on climbing accidents, and I have seen binners that have failed....overussage of the binner can cause a groove to form and weaken the binner further. I have also seen binners that have been bent...probably from falling on them many times or overusing them to the point where the gate no longer catches right, but you sounded like you were talking brand new gear with no wear

A rope was shedded this way some time back in Queensland Australia. I thought it was impossible but there is a configuration where it can happen. Very rare but possible. It takes seconds to check.

The whole topic is way over-wrought even by genuine first world problem standards.

Hasn't that been the MO for the Lab for years now?

just checking late on this thread. not sure why it's so emotional.
I understand cracklovers set of circumstances. strange things could happen to a pair of biners if they are protruding over an edge like that.
but practically - that type of set-up is a safety violation. a TR should NEVER be set up so the biners just poke over the top of the rock. the biners should always hang loose and free - beyond the edge.
i'll leave it to people to debate the in's and out's of the argument. cracklover's scenario simply reinforces that the age-old safety standards are true - if you don't use bad set-ups with your hardware - you don't get bad results.
BTW - I always used oval biners for TR's, and generally preferred locking biners anyway. if I used the oval biners, I usually set it up as 3 biners (not two), with the middle opposed to the two outer ones. the reason for choosing oval biners is that D-biners can do slightly odd things, just like cracklover showed - they are a bit more prone to working their way inside of each other.
cheers,
dT

It's so emotional because a certain percentage of rc posters live there entire life mitigating against "what if" events, no matter how remote or unlikely the occurrence of a given event. Underlying this is the misinformed and breathtakingly naive idea that risk in rock climbing can be reduced to zero.
I didn't see any such scaredy-cat posters getting emotional in regards to this thread. The only folks who seem to be up in arms are people like you and Healyje, tilting at windmills.
GO
