What diameter prussic cord

[NOZ]

If you really want prussik cord - you can get it from arborist suppliers http://www.teufelberger.com/en/products/arboriculture/tools/sirius-loop.html
It is more flexible than the equivalent diameter low stretch cord.

10mm sounds to thick for me. Even if it is flexible and grips the rope, it seems to be unnecessarily bulky.

This was purely an example and is available in other diameters - it was the first hit in my search.

With respect, Noz - I did check the technical specification of the Sirius Loop before posting, and according to the manufacturer, although it is available in various lengths,  it is only available in 10mm diameter.

With respect Langcliffe - Teufelberger are not the only manufacturers/suppliers of prussik cords.

Many apologies, Noz. Mea culpa.

I thought that you were drawing our attention to something special, not just any old prussik cord.

When caving don't wear anything around your neck that isn't easily snappable. Abseiling with a cord around your neck is a really bad idea.

I never mentioned my neck. Benfool assumed that.

Around your neck, with the knife, why dont you also have a tibloc? Seriously, these days, with the development of very small emergency jammers there is absolutely no need to carry something which you have specifically designed as a prussic loop. Indeed this is a outdated practice from moutineering and climbing and does not really apply to caving.

Anyway, if shit hit the fan, you have the rest of your SRT kit to play with. A pantin, or even a decender could easilly be turned into a backup jammer if needed. A prussic loop certainly wouldn't be my plan B, maybe Z......

Yes I may have my SRT kit to play with and a mini-traxion and a pulley.

This thread is about Prusik Loops and it so happens that I always have one anyway: as I said, I carry my knife on it (and no, it's not around my neck either) and as I always have a knife if I'm going to be anywhere near a rope, why not use a 6mm cord which has other uses rather than some spare bootlace?

Prusik Loops weigh nowt, cost next to nowt and have uses other than Prusiking. Ever tried using a Tibloc or Pantin or spare jammer as a deviation cord or as a French Prusik below your non-autolock descnder or to replace a broken tackle bag cord or as an improvised chest harness, etc. etc.?

How clean is that caving suit!!

Utility pockets, like Batmans belt.

I've got 6mm cord for prussic loops. It's slightly less grabby on the rope so easier to move and has about a 50% greater breaking strain.

I've used loops on expo when my SRT kit wasn't at hand. There was a 3m drop that looked like it could be hand-lined. Abbed down, explored, couldn't hand line it but was up in a minute with loops and a belt. One of the loops was used for a deviation later and the other for a somewhat dubious rebelay.

I also sometimes keep a meter of 2mm cord with the loops as this can be used to saw (one loop round, move left and right) through a tensioned rope in < 30s.

Thanks for all the replies/advice folks. I'm going to give the 5mm a go next time rain stops play and I find myself at the climbing wall. I've also had the very kind offer of a length of 6mm from a fellow caver. Should be interesting to compare them.
