Ken, at least with a ring (as compared to the quick link, cold shut, or piece of chain), the ring can be constantly rotated so the rope abrasion is distributed about the ring's circumference -- giving it durability many times longer than the link, which forces the rope abrasion to a confined area. Anyway, good suggestion about how to fix the anchor when the ring does get worn.

That is a good idea for replacing the rap ring. Obvious, but why didn't I think of that?

Another solution is to use old carabiners and replace them as they wear out. Most of us have a number laying around. We have been putting the anchor hangers that Fixe provides without the rings and putting biners in them. We were using quick links in them but threading is a little less easy. With the biners everyone is motivated to replace them when they start getting worn.

The only problem with using carabiners is that people think they're booty and take them home. There is nothing more frustrating than equipping an anchor only to find someone stole the hardware a week later.

Just wanted to add that for #1, the reason there are an even number of quicklinks, two each bolt, is to ensure that the rope does not kink!

I like Eric's idea. If someone booty's the biners from the Fixe horizontal hangers, they can't get down.

Fixed draws/biners is popular in pure sport areas (Rifle), don't get booty'd. But don't get replaced that often either.

Here is an Idea:
Some one said that the Rings last a lot longer than the Links because they distribute the wear around it. So, wouldn't it be a good idea to put a ring on the end of a quick link? That way they ring can just be replaced when it gets worn. And the rings are cheaper too.

If you use a stud bolt with #2, you don't have to remove the bolt to replace the hanger. Just unscrew the nut, replace the hanger, and retighten the nut. I've upgraded a number of anchors this way, replacing Fixe single-ring anchors with double rings or lowering hooks.
