What's the max load you can put on a rappel anchor?
Do you ever wonder how strong your rappel anchor needs to be?
Answer, not very strong. Even if you bounce around like a special forces cowboy and weigh almost 100 kg / 200 pounds, turns out that anchor is not gonna see more than about 3 kN, tops.
If you rappel fairly normally on a dynamic rope, the anchor shouldn’t see much more than your body weight.
The chart below comes from a nice article from Black Diamond with a collaboration from IFMGA Guide Mark Smiley. It's a good read, here's a link.
Also, in the article is an interesting test of different sorts of buried deadman snow anchors. (Hint, you want to bring a 2 x 4.)
