"FIXE (Tech Rock) issued a warning for faulty anchors due to stress corrosion cracking. This is important because FIXE is a leading manufacturer of anchors, and they are widely used. FIXE cannot limit the problem to one single production batch and all top chain anchors of the manufacturer made of stainless steel may be affected. 

We have included information from UIAA, Tech Rock, and the German Alpine Club (DAV) which include the most complete and extensive information we could find on this important warning notice.

Below is content from Tech Rock, DAV, and the UIAA. OSI is not responsible for this information.*"

Thanks for posting this. This might be a good reason to build a bolted anchor with your carabiners clipped directly into the bolt hangers instead of clipping the rap rings or chains.
