" Sliding X" - Ancoragem equalizada

©acoelho

"To equalize alpine anchors, many climbers create a socalled “magic X” (aka “sliding X”) by putting a twist in one strand of a sling connecting two pieces of protection. This system has the advantage of “auto equalizing” the pull on the pieces as the belayer moves around. The disadvantages are that the magic X is not redundant, and in most cases the slings climbers use are weaker than the bolts or pieces of gear they are equalizing. Why double up on what’s strong— the protection—and not on the weaker slings?" by Ian Nicholson at climbingmagazine
