Prusik loops

[sid69]

What's the rules for using a prusik loop I've tied myself using a double Fisher mans bend do I need to use a manufactured one.

[Dan Maynard]

I've never used a manufactured one.

It is going to depend who makes the rules where you work, but there's nothing fundamentally to stop you knotting yourself as long as you are competent. Judging competent is another sticking point in some sets of rules.

[Doug Tait]

Don't know about rules but I've always tied them myself. Some people I've worked with don't like it but in my eyes you rely on knots you've tied yourself all the time, why would a prussic loop be different.

Always tied my own, can't see much difference in tying a prusik loop or a bowline to clip in to. How can anyone say your safe to tie one knot and not the other

Depending on what it's used for, I like to cross my cord over itself once before tying the fisherman's, giving an adjustable loop either side of the knot. One half is then cinched up tight against the biner, leaving the big loop to throw around the rope. This probably has a name, I'm sure someone with a bigger brain than mine can identify it.

 

That's the end of this story.

Thanks for that info everyone.

Sliding Double Fishermens, or Grapevine bend, not a knot.

All bends are knots, all hitches are knots, and the term knot can be used interchangeably when talking about either, especially in a casual or conversational setting. But thanks for reminding me of the "sliding" part of the name. I could have sworn it had another name though. I'll keep looking.

I have always tied my own. I was taught to tighten it up so hard that it cannot possibly ever ever come undone. Like 200kg pull. To make it LOLERable stick a waterproof label with date of tying on it and then seal in with heat shrink wrap tube.

 

My hot tip is to remember to put the shrink wrap tube on the loop before you tie the knot.

 

The sliding one cannot be tightened up and is therefore in theory vulnerable to working itself loose. Even if you adjust it to its final loop lengths then tighten it, it doesn't cinch together quite the same.

Only problem with that is you don't tend to adjust where the prussik grips the rope so wear is localised to that one point if that makes sense.
