Going climbing in Thailand? READ THIS FIRST.

If you've been to Thailand lately you'll know that many of the top anchors consist of two titanium bolts, each threaded with a piece of rope or sling, which are then threaded through a single STEEL lowering ring on the other end. This is done, of course, to minimize wear on the bolts from people lowering off them directly.

Recently one of these rings has been found to be cracked completely through.

I don't want to cause any panic but because this is a single point of failure, please INSPECT the ring at the top of your climb before you trust your life to it. If you find a cracked ring, back it up with a leaver-biner and please let one of the "locals" know.

This ring is being investigated. It could be stress corrosion cracking (SCC) in which case we have a wide-spread problem. However, it might just be an isolated manufacturing defect.
Guideline #1: Don't be a jerk.
