I am not sure what the rings are being used for, for I don't use them for anything. If they are being used for climbing, how are they getting so much weight on them? If they bare being used for rigging, maybe consider a proven steel carabiner. 50KN or stronger always for rigging, no exceptions. 23KN or stronger for life support, no exceptions. Those are the rules I live by and and do not use a product until I have tested it. Stay safe.
As far as I know they consider the subject closed Keith. They sent test results showing breaking well within specs and I haven't heard of any others breaking at sub 23 kn pulls. I will give them a shout to see if anything is new on this.
ps I will be getting my future rings from Italy regardless of what happens with these. I know for sure the testing is more intense and I get test results from each batch sent.
A little late maybe to bother getting into this thread, but I'd like to offer up my guess, if you care to test it out.
If you have access to a hardness tester, I'll guess the rings that cracked without deforming are much harder than the rings that deformed and didn't break.
That would indicate one of two things; the rings that broke missed a forging... not really likely, since the size would be amiss, or...
The rings that broke missed a heat treating. Looking at the pic, the broken ends look very "grainy". Heat treating, among other things, controls grain growth. It also tempers the metal to a specific hardness range- you want it to bend before it breaks.
I thought this forum was about injuries, not gear, or I would have lurked in here sooner. So what are the conclusions for all this? Discard all GOLD COLORED aluminum rings? The rings I have are silver and from Wesspur or Sherrill. Is periodic non-destructive testing possible/practical? If I trust aluminum biners I don't see why I shouldn't trust aluminum rings as long as they are made correctly. Use steel for rigging.
Oh heck, it was near the top so I didn't notice how old this thread was... sorry...
i had bought one of those saddle's from the recall and with out knowing i just took the ring off anyways cause i didn't like it because i like to custom my saddle a little bit.i used the ISC snap biner and its awsome and i also took that stupid black sleveing off to make it a smoother roll. other then that AWSOME saddle!
