prussik knot

No, it doesn't work too well trying to heat seal the OP because of the aramid in the sheath. The polyester core melts ok, as does the polyester in the sheath, but the aramid burns. Made a right mess when I tried it. I think whipping is more reliable than heat sealing in the long term anyway, as the melted polyester is brittle and starts to crack.

If you're closing the loop with a double fishermns you're able to tweek the length to your exact liking. Just tie the one fishermans, place the prussik and adjust the length as required. When you are happy, tie the second fishermans and loose the excess with a red hot stanly (or proper tool if your posh). For a slightly more gucci finish you can pre position a couple of bits of heatshrink to lock the little tails down onto the standing parts of the line?

Guys can I be a bit pedantic here what you are talking about is a Prusik hitch not a Prusik Knot the Prusik Loop is tied with a double Fishermans Knot then formed on to the climbing rope as a movable Hitch. I know I am being a bit nobby about this but its one of my pet hates, sorry also check our Prusik on Wikipedia it appears many of us call it the wrong name too Wiki quote:

 

A Prusik ( /ˈprʌsɪk/) is a friction hitch or knot used to put a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, and by arborists. The term Prusik is a name for both the loops of cord and the hitch, and the verb is "to prusik". More casually, the term is used for any friction hitch or device that can grab a rope. The word is often misspelled as Prussik, Prussick or Prussic, as it is a homonym with the term prussic acid.

 

The Prusik hitch is named for its alleged inventor, Austrian mountaineer Dr. Karl Prusik. It was shown in a 1931 Austrian mountaineering manual for rope ascending. It was used on several mountaineering routes of the era to ascend the final summit peak, where a rope could be thrown over the top and anchored so that climbers could attain the summit by prusiking up the other side of the rope.

In the past I've used 1.6m for my strop and 1.8m for my mainline prussik, try a sliding prussik to stop it coming off you mainline krab. Had a few hairy moments when i've clipped on and noticed the prussik missing.....yeeehaaaaa
