It is used in many different situations on both single rope and moving rope climbing systems. For example, it is used in combination with the Hitch Climber pulley to ascend and descend on moving rope systems. On single rope systems it is used in combination with hybrid climbing devices like the Rope Wrench and Hitch Hiker to ascend and descend. It is also used as a progress capture brake on mechanical advantage pulley systems.
@@ericforsman7787 I am specifically interested in this for 3:1 Z-Drag type swiftwater rescue scenarios, both on the progress capture end near the anchor and for the traveling pulley out on the line. The prusiks normally used are almost always the weakest link by a long shot and there might be reasons this is good. If we're jumping to a 7mm-8mm VT Prusik, that is obviously no longer the case. Any thoughts or demonstration videos of this in practice out there that you're aware of? I haven't been able to find any.
Hi Andrew, I am not aware of any demonstrations that use the VT for progress capture, but arborists commonly use the VT or other such hitches for progress capture on lanyards and canopy rope systems. For progress capture at traveling pulleys I sometimes use a VT, but my favorite is with a mechanical device like the Petzl Croll or a handled ascender. That way there is no setback and you don't have to worry about the friction hitch getting wet and binding up on the rope under a heavy load.
For 7/16" rope I usually use 8mm hitch cord, but 10mm is fine as well. In both cases I would use 4 wraps at the top, and then adjust as needed after you have experimented a bit. The VT is kind of a fussy knot, and you should test it out down low before you climb high. And when descending, always keep your brake hand on the rope when you release the knot with the other hand. That way you can control your descent and be ready to brake in the event that the friction hitch is too loose. In addition, you should always push up and "set" the friction hitch when you first put your weight on it at the top of your ascent. That way it will grab the rope.
Check out any arborist supply catalog and you will find lots of them. They are a standard item used in moving rope climbing systems. They are also used in many other situations, such progress capture in mechanical advantage systems.
Thank you. Your explanation is excellent.
Thank you David. Glad you found it useful.
Thanks, i felt insecure tying this knot and your explanation helps a lot!°
most excellent ..
Hi, I'm Italian but this node is used to slow down the descent on single rope?

What diameter hitch cord would you recommend with 7/16th" 16 strand climbing line? I'm 160lbs, should I do three wraps?

Newse Neus i see most tree gear sites recommend 8mm for 7/16" rope and 10mm for 1/2" rope
I use 8mm bee line hitch cord on 11mm sterling htp and it works great! I use it in conjunction with a rope wrench!
best, simple, well explained, thx
Thanks Kubo!
I've never seen an Eye 2 Eye Prusik rope.

@@ericforsman7787 Thanks, I found some on Amazon.
Thank you. Your explanation is excellent.
Thank you sir!
