Rope abrasion, when to replace, etc.

Hey all, 

Did some TR climbing today on a 7 mm cordolette anchor, and noticed that there were a few spots that showed abrasion afterward. Not through the sheath, but definitely enough to notice. I think it may have been friction from rubbing against the mat that I used on the edge. 

While I historically I have used the general principle of "if you have to ask, you should probably replace it", I am curious about any other guidelines on when things are clearly in need of replacing. 

I've attached a picture for reference. I welcome all input. Thanks! 

Less the core is showing you're totally fine. Just inspect it every time if you suspect its getting rubbed a lot.

Looks good to me!

And since it's a top rope anchor with a cordelette, you'll be rigging it so the failure of any single strand is safe, right? :)

What rm said! Dat SERENE

Any type of cord you are looking for 2 major things. Is the core showing and when you fold it over in the picture is it flat. Given all ropes will fold over differently so it is good to check it out when you first get the rope and use that as a baseline for checking it later. You don't want to wait for it to go completely flat but over time it will soften and fold over a little more before it is bad.

If your rope looks like this guy

you probably won't die

But if you see his white guts 

you could fall on your butts!

Thanks for the info all. Very helpful indeed!
