This can be solved by adding "limiter knots" approximately 6" from either side of the sliding X's main point. A sliding X can be used as part of an anchor, but by itself it is not sufficient. The master point of this anchor has two anchor shackles: one for the mainline and one for the backup. If that sling gets cut, adios. You would use limiter knots to lessen the shock load caused by the extension from one piece failing in that configuration. As my backups I used blue nylon slings just for the mock up. With so many products on the market, it’s hard to know Alpine draw (single or double depending on bolt anchor spacing), clip bolts and extend sling, sliding X with a locker. If you are going to use a sliding X type anchor, use two slings so that you are not dependent on a single strand of webbing. Figure 3.

If you rappel smoothly on a dynamic rope, the anchor will only see about 1-2 kN, and the direction of force will always be down. While a quad can split a load fairly evenly between two arms, a sliding X might only achieve a 70/30 split since the twist in the sling at the master point creates friction which puts most of the load on one of the two arms.

Sep 23, 2014 · I was climbing a multipitch route the other day with a new partner, where every anchor was bolted. Step 5: Inspection and Testing. Mathematical data suggest the potential shock loads created by extension (even limited and minimized extensions) can be severe. This method offers extremely good equalization, but fails in reducing extension in the event of an anchor failure. Once you secure it to the beam using the integrated adjustment buttons, simply connect your Self-Retracting Lifeline (SRL) or lanyard to the rotating D-ring and you’re ready to work.

Anchors are different and there are some points you should keep in mind. I think it fair to say that the results suggest that you cannot, in general, count on any equalization advantage from a sliding X over some fixed system, and when you get to three-anchor situations the sliding systems can be far worse than fixed ones.

The Sliding X anchor can be tied with a sling or with cordolette. On the other hand, self-equalizing anchors like quads or sliding x’s will adapt as the direction of pull changes over time. There are many ways of incorporating the sliding-X into an anchor. But in a pinch, especially on easier terrain, it will do.
