How do you anchor a cordelette to a carabiner?
(A good rule of thumb in anchor building is that the anchor master point should always be at waist level or higher, ideally around your chest.) Solution: rather than the standard method of clipping the cordelette into the carabiners, instead pass one or even two loops of the cord through the carabiner, and then back to the master point.
Why do cordelette anchors stretch the shortest leg?
If you build a cordelette anchor with legs of very different lengths, a majority of force is going to go to the shortest leg, because that’s stretching less than the other two. If you have to do this, try to be sure that the gear you have on that short leg is as solid as possible.
