Neat trick for choking climbing line on limb

[Pedroski]

You probably already know this, but I saw this neat method over on TreeBuzz for choking a climbing line on a limb with a krab, that completely avoids the krab being cross loaded and is also easily retrievable provided you add a retrieving line to the krab or leave a proper long tail. I'm not sure if it's permitted to link to other forums..... if it is ok then I'll post a direct link to it.

 

But in meantime, all it involves is tying a bowline on a bight (see Bowline on a Bight | How to Tie a Bowline on a Bight | Boating Knots ) having each loop of the bowline either side of the climbing line, and clipping a krab through it.

 

Here are my pics. Not very good, but they show the idea.

 

First picture is the bowline on a bight.

Second with the loops clipped around climbing line with the krab.

Third cinched against the limb (well, my arm, but never mind).

Fourth with a retrieval line attached. Alternative retrieval would be using long tail on the climbing line.

 

Another great thing about this is that once you reach the tie in point it's easy to release without having to pull the climbing line all the way through a running bowline, and so the line can easily be relocated.

 

What you think?

Am I missing something? How would you use that with Ddrt? I could see its use in SRT.

[Pedroski]

Use it for an SRT ascent, then it's dead easy to switch to DdRT. Tie in, remove the krab and clip the bowline on a bight into your harness, coil up your retrieval line, attach split tail to the line you just climbed, and away you go.

 

To descend, set the tie in point again using the bowline on a bight as shown, attach the retrieval line, rapp down the climbing on a fig 8 or whatever, and retrieve the line.

I see. I would just put in an alpine butterfly and choke it off. It's retrievable from the ground as long as you have a straight directional pull and not through several redirects.

Alpine butterfly good, but when you reach TIP and want to switch to DdRT or relocate TIP you've then got to pull climbing line all the way through the butterfly haven't you? Rather than just being able to unclip it from the climbing side?

Nice, feel to link from the Buzz.

Thanks The thread is here TreeBuzz Board: choking carabiner and the krab through BOAB is detailed in SingleJack's post, toward bottom of first page.

I meant bottom of page 2, not 3
