Dear All,
I just bought 6mm cord to make prusiks loops and realised my old ones are 5mm. There are lots of conflicting opinions online about prusik cord diameters e.g. should be 50%, 70% of single climbing rope. Before I chop it up, can someone testify that 6mm is good, in both prusik knot and kleimheist for abseiling backup and prusik for rescue/belay escape, on a 10mm rope?
Thanks.

You can make use rope on rope and and still get a working friction hitch. 6mm should work fine with fairly standard friction hitches on a 10mm. Cut them to size after you've tried it out.

In reply to Alan_on_top:

6mm is fine. As would be 5mm. As would be 7mm. As would (if using the correct hitch and being sensible) 10mm cord, 10mm dynamic rope or nylon slings.

Don't worry about it.

In reply to Alan_on_top:

As has been said it will work fine. But the knots will use a little more cord, so try it out before you cut it to length.

In reply to Alan_on_top:

For 10mm 6mm works very well; for 8mm 5mm would be better.

In reply to Alan_on_top:

THANKS.

Thanks for your advice everyone. The 6mm works fine on my 10mm. It knotted very well too as it's quite soft - Tendon being the manufacturer.
