Triangle and n-way slacklines

I got an e-mail from a reader asking if we could do a tutorial on multi-directional lines (triangles, pentagons, etc).  Luckily today was our mid-May meetup, so I whipped up a 3-way line and brought the camera.  Here’s a quick video howto and some shots of the line in action.  For those who don’t want to watch the video, here are the main points…

  • The lines must all connect to something that is rated for multi-directional loads.  I used a 2″ MadRock forged rappel ring rated for 32kn (7200lbs).
  • You could affix the lines to the center ring by clipping into it, but that would make the lines turn awkwardly, so I used my “double ring” method (patent pending, haha).
  • Tension the lines equilaterally — pull a bit on one, then a bit on the next, on the third, then back to #1…
  • A person on one line can be felt on others but mostly in the vertical direction, not laterally, so tandem walks are simple

    Thanks for the quick reply Adam. Same day delivery! Trying to get the hang of the double ring so I can do it much quicker, first try took a few minutes and a re-do. Interested in seeing the 3+ line setup.

    Hey, where can I find a 2″ rap ring like the one you used here online? I have looked, but I’m not having much luck…would a stainless steel one work? Thanks

    Mad Rock makes/sells them, and also ClimbX sells a rebranded version. Both of these sources may or may not be out of stock when you click the link (about 50% of the time they are out of stock… and it takes a few months for stock to replenish). Stainless steel will work, but make sure it has a rating stamped on it. The ring must be rated for 18Kn or more. If it has no rating stamped on it (such as those RenoBclimbing sells, be wary — I have bent his rings in the past, and do not trust the “44kn” rating he says they have).
