    Unhappy Zing it Prusik knots

    So I'm trying to make myself a tarp ridgeline and I'm running into an issue. I'm using 1.75mm zing it. My prusiks aren't holding. They hold to a point then start slipping. Can the zing it be prusik'd onto the same type of line? Or should I be using a larger line for the ridgeline and smaller diameter for the prusiks? I'm using 3 turns. Would 4 help?

    Zing-It/Lash-It and other aramid fiber cords are really slick. prussiks work best with a smaller line wrapping a larger one. It doesn't work as well using a line knotted onto itself with the prussik. However, you can just use more wraps to get more friction. 4 may work, maybe you'll find you need 6, just keep wrapping to increase the friction until you feel it's right.

    Zing-It/Lash-It (and Amsteel-Blue; i.e. Dyneema/Spectra) is made of polyethylene not aramid, but it certainly is slippery.

    Thank you for the correction. I guess I have more reading to do.

    How many wraps are you using? 3 wraps slips around 30 pounds when using 1.75 on 1.75. 3 wraps using 1.75 on 2.2 slips around 40 pounds.

    4 wraps using 1.75 on 2.2 gets you over 50 pounds.

    Try the blakes hitch if you dont want slippage.
    I am not a gram weenie. , But Im starting to see the merits!!!

    The Klemheist may work better if you are only anticipating pulling from one direction. I use that on my figure 9 carabiner for my ridgeline and it works much better than a prusik.

    Well, I got it working now. I used 4 wraps, but I think the main problem was that my prusiks were kinda sloppy. Once you make them nice, neat and tight, they hold find. Now I just need my new OES MC Dlx and I'll have a fine setup.

    prussik loop

    I wasn't sure if you can create the zing it prussik loop with a double fishermans knot or does it have to be spliced. I am imagining it is tough to splice that thin a line.



    Thanks,

    Steven

    It is a little tough to do, a good pair of glasses helps, but I've done it. It can be done, after one or two, it gets easier. I made 12 of these a couple weeks ago.
