    The better option if you don't want the prussic or other friction knot to slip under tension is to use a smaller diameter line for the prussic loop.

    That is how they are designed to work.

    It uses the same prussik loop, I have been successful with braided mason's line..... works on zing-it, too....
    I agree with Mr. Sawyer here. The klemheist will hold on some of the slipperiest of ropes. Some times, you have to add a few extra wraps, but if all you have out on the trail is the same rope, then the Klemheist is my go to knot.

    Mr. Sawyer?? Who's that...

    The reason The Klemheist works with fewer wraps, I THINK, is that the wraps tighten up in one direction only, thus making the knot effective with half the wraps of a prussik.

    I've done prussik's to zing-it. It just takes 4 wraps, and like others said above, it works best with a smaller line wrapped on a larger one... I find wrapping prussiks more than 2-3 times to be hard... but it's probably my fat fingers and failing eyesight.

    What great info! I think I need to work the "newness" out of my tech line, or work on my prusik technique more.

    I wonder if it would be better to try a prusik loop made out of just a single inside strand of 550 cord on the tech line, rather than my three strand braids?

    Anyone know if a single strand of 550 would be strong enough to hold the tension of a tarp ridgeline? By strong enough I mean both breaking strength and prusik friction strength.

    I tried that before, a single inner strand from paracord for the prusik, and some solid 3/16" generic cord. The prusik cord was way too small, and wouldn't loosen up after loaded. Had to cut them off.
    The real way to use a prusik, is with a smaller diameter cord, that;s hollow and soft, to really grab. Although, it's also because people climb with it. To hold up up your tarp, you can use whatever you have.

    Below are pictures of a prusik I use on my molly mac gear box, that supports the weight of all my gear. It's with that 1.9mm tech line from diy gearsupply. Works great.

    Just be careful not to adjust a mason line prussik too quickly or the friction will melt the nylon.

    Thanks for the heads up, but not to worry, I have never moved that fast, not that I remember anyway.

    It must be my if 3 wraps is good, then 6 is great. I guess less is more.

    Everything held nice and tight, even through rain and wind.

    Here's some pictures of it all set up! First time I had it all together so I'm all proud and happy and stuff

    I like this knot as well. I have had issues with it locking up though. Usually when its wet. As long as a prusik is wrapped on a larger diameter line it works fine. One solution I learned from my old hennesey setup. It really assisted a prusiks hold and reducing its potential to lock. After you wrap the line if you wrap the tail of the prusik through the stationary end of the prusik it creates a sort of hitch that keeps the wraps taught on the line.
