I was staring at a series of pictures in a book for a long time, trying to figure out how to make the second set of loops. Watching 10 seconds of this video made complete sense. Thank you! My sanity thanks you as well...
Thanks. This is very useful. Sporting goods stores are now selling this Prusik Knot and rope set-up to hunters as a safety line for their tree stands. The going price is between $25.00 to $30.00. You can tie it yourself for a fraction of that cost and do it in the field if needed.
Excellent presentation!!! I liked how you used a dark background to accent the clarity of the ropes. And thanks for the commentary. And mainly, thank you for taking time to do an excellent, neat setup and video.
Prusik knot is the handiest knot to use if you're the average homeowner working on a metal roof. I've used it several times on my 12/12 (45 degree) steel roof.
Great knot to know. I used this all the time when climbing, on technical climbs, before mechanical devices became available. I've used it in some rescue situations to tie fast loops on a rope.
Excellent. So often, people think its about the rope work. Its about the videography ! Great lighting, large lines which contrast with backdrop, use of 'point of view', good volume and sound, not too fast or slow, hands not in the line of sight ... Thanks
i used to use the distel knot when I was in the tree service.. very trustworthy for controlled descent... Also not hard to move up when you were ascending
This is a self belay using a Prusik. Also always tie it with the knot closer to the mainline so you never have to worry about clipping in near the knot
Eyeballs don't weigh much so shoe lace is overkill. 10 lb fishing line would have been fine and still plenty strong to bring his buddies namely nose and ears.
Good video, but my preferred is a 10mm lead, 2) 8 mm prusik loops; each tag ends buttoned up with a stopper knot (top & bottom) on each double fisherman's knot, then place fisherman's pointed to me, rotate loop 2 hand widths (preference left) & make prusik (two on single lead or one on each for double line climb). Prusik climbing can be nice way for upper arm training in low ropes, climbing up & down as a single rep & repeat, attempting to do more every other day (resting arms a day in training is needed too, but that can be a core or leg day).
I like this video! And i inspired to make some video like this on my channel, let's check ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sWa5FaCCqVA.html
I learned such bindings in sailing school and sometimes you had to sweat to gain experience. ❤Hey kids JUST be aware that it's not that easy watching the movie 🥃🍀
That is the minimum number of wraps you would want for a prusik- more wraps will generally be better. Most climbers like to see 5 pairs of wrap. It’s also incredibly important to note that you DO NOT want to have your double fisherman (or whatever connecting knot) at the point of tension where your carabiner will sit. I know you said that but the first half of the video has the knot at the bottom of the loop which is not good and it’s worth saying again. It’s best to offset the knot from the beginning.
5 pairs of wrap?? It would give to much friction to pull yourself up... Im a professional tree climber and i wrap it two times to reduce friction (i weight 70 kg)
If you are using a prussick as a conditional belay make sure you know how to transfer your weight back on to your descender if you do take a fall on it. Once weighted you just can't simply reach up and pop it loose. Always carry two prussick loops with you.
Yes, I´ve seen a lot about such knots, but never a video on how people actually descend (there are different styles, but I know only little about them)

A interesting variation of this to tie the Prusik on itself. Now you have a adjustable loop that you can use on tarps or for boat bumpers. You need to tie the gripping loops on two fingers together first then then work the other end of the loop through the wraps as you remove your fingers..
Thanks for sharing! great video and really clear steps 👍🏽 I'd really like to see a follow up video on how easy this is to use on a practical application... maybe like climbing back up a well 😅 (asking for a friend who, as a kid, fell in down a bat infested well. He's a billionaire now.)
I know you say you wouldn't use paracord for a Prusik but it is used and can be used when necessary. I've used a pair of paracord Prusik knots to ascend up a line to do a recuse. It wasn't ideal but it was necessary and safe. The biggest concern isn't the load on the paracord but making sure the ascending rope is secure and won't slip under load as you ascend.
The prusik cord doesn't need to be "just smaller" it should be 2/3's the size of the rope you will be attaching it to. for example he is using what looks like 11mm rope so he should be using 7mm prusik cord. Which is what he is using. He could go up to 8mm as well.
This was literally the most confusing part for me.... in srt either I wasn’t paying attention or the teacher never went over size difference between mainline and grab or brake
Actually, if the prusik cord needs to be 2/3’s the size of the rope it’s attached to, then the prusik cord does, in fact, need to be just smaller than the rope. I just did the math, and it turns out that he was right all along.
One time I built a log mansion in Yosemite west with a gaggle of rock climbers. And we used this knot to hoist large log like logs. My dad was a member of the international knot tiers guild or whatever you call it. I'm a heavy construction guy so I'd rather trust my life to a piece of extruded aluminium( OSHA approved it). But I can attest that I've seen this knot do crazy stuff with three to four manpowers. Wish I knew more knots but I don't so as the old adage goes tie a lot.
Good explanation of the knot, but the title says, "How to Ascend a Rope...". That's not what you covered. You might consider changing the title of your video.
Gila Monster you can easily ascend with one prussik while you walk on ice/rock, by catching your balance, moving the unloaded prussik forward and then walking next step (works real fast on slopes up to 55 deg, its just like using jumar on those); on steeper slopes you use 2 prussiks, usually one to belly, the other is leg-pedal and you move the unloaded one higher while loading the other one - also quite fast and works well - again it's like using two jumars, one of which is belly other is leg-pedal ;-)
Dude! You had me waiting for 3 minutes to see that darn double fisherman's knot not ending up in the carabiner :D (I always pull one side right before tightening the constriction, but hey, nicely done anyway :) About paracord: I would make do if nothing else were around, but agreed, we all know that you don't hang under a parachute with just ONE strand of parachord, right? About the diameter of your prusik: IMHO 6 mm is about ideal. Using larger diameter for a prusik may seem more convenient because it's easier to loosen the constriction, but at the same time the amount of friction gets spread more through the constricting loop when using a larger diameter prusik loop. I think I would still do nicely with a larger diameter loop, because I'm comparatively heavy, but lighter climbers / prusik ascenders ;) might find some dificulties as the laws of physics do not favor them as much in that respect (Sometimes I wish ;) ) Apart from the missing ascending bit (rename the vid?) a great vid explaining the tying and the working of the prusik loop.
also- he said that the greater the variation between the cord and the rope diameter, the more likely it is to slip. Isn't that backwards???? A smaller cord will bite MORE???
Great advantage over the bite devices. Just not approved but as long as you’ve got an ascender clipped on somewhere most inspectors don’t know the difference
Could you use the prusik knot with a bigger cord and the ascending line smaller? I’m thinking of using paracord around a pull string for pulling through conduit. A slick sliding handle.
Cambria399 For a minute I thought I was the only one that caught his hiccup where he should have described the knot as bidirectional I’m OCD about this kind of thing--drive my wife crazy.
Good instructions ... I just don’t know what I’d use it for other than what mentioned which I didn’t understand. I am looking for a certain kind of night for a specific project but nobody seems to ever show the output of the how the knot is not used visually
Nice video. A good option for tarps too off of a ridgeline. I like to use a shoft shackle knot instead of the fisherman's knot so something can easily be attached within the loop -- not for climbing though.
can you use this not going around two ropes. in other words if I had my life line around a limb in the tree and I wanted to come down that rope could I wrap it around both of them
I use the first Shake on my paracord for my Ridgeline when I go camping do the idea that holds my tarp tight and I have no problems and I use Bank line
I been using a 7mm prusik cord rated for 2500 lbf in my lanyard to adjust the length with a friction knot I wight 215lbs. I will like to continue using this for the climbing hitch. Do you think that this is good enoug to use it in this system?
m ro but then you'd be grabbing the brake end of your rope and your ATC would stop you... don't see a problem here. you have to grab above it to pull it down. unless it's the one above you then you're pushing it up and your hand wouldn't be above it.
You are right . I was a high rise window washer and this is exactly what happened . My working like broke as I was repelling and I grabbed the knot and rode it to the ground . 83 days in the hospital . Year off work . Lucky to be alive . Even tho I knew to let it go . I could not in the moment .
i have a need to do this with the same diameter cord & a rap around a (cpvc )tube. the tube i very slippery and rigid surface. what kind of knot (if any) can be made?
In a lot of your vids you use the double fisherman's knot to create a loop. Is there a reason why you do this instead of a sqaure knot, or something like a sheet bend knot?
