Prusik cord..

Recommended Posts

Hi there, i have used an eye to eye 10mm diameter prusik cord to make a hip prusik for use with my flip line.

 

Bit worried though, as from what i have been reading using a 10mm cord on an 11mm flip line will result in me falling out of the tree..

 

I have a 10mm cord for a hip prusik with my 11mm rope lanyard and that grips in a BIG way. Do you think it will be ok for my flip line?? [the 10mm cord on the 11mm flip line i mean]

 

Thanks all

Personally I use thinner accessory cord with a 11mm rope. As for using 10mm, give it a go at low level 

, if it grips keep it, if it doesn't change for thinner. Your hardly going to plunge to your death..... if your only 2ft off the ground trying it.

Proper prusik with 6 wraps..

 

Do more wraps necessarily mean more grip?? I tried with four and that seemed to grab harder than the six??

In my experience an extra wrap gives alot more grip.

Does it grip and release? If it does, no problem. If it doesn’t, drop the cord size or change the hitch. I got surprisingly good performance the other day from a klemheist on some quite similar diameter rope/hitch. 11/10 isn’t textbook but it’ll work if you can be bothered to find a knot it likes.

It was just that a few seconds after tying it, i gave the thing a good shake about to sort of simulate when you whizz up a tree sometimes without putting any weight on the hitch and then when i did, and expected it to grap.. it slipped.. ooerrr..

 

On my 10mm/11mm rope lanyard, same prusik cord, it grabs so tight you have quite a job to get it to release sometimes.. I would much rather this i must say!!

Often prussic cord and knots take a bit of time to bed in. They tend to grip better once there's a tiny bit of wear. You might need an additional wrap initially, which you can then take off again after a while.
Also I think there's less grip on a wire core flip line anyway, regardless of cord type or knot. Due to the rigidity of the wire cable in the middle.
Personally I find a thinner prussic cord much nicer to use for all applications. I've got 8mm Ocean Polyester, works lovely.

I will give it a go in practice, and then maybe get some 8mm as this does seem to be better...

 

Funnily enough, it was an Ocean one i was thinking of getting..
