extra lanyard prussik?

At the ITCC Hawaii, I noticed several top contenders sporting an auxillary mini prussik near the clip end of their lanyard. I would theorize that it might come in handy to terminate your line on a second anchor so that you could extend the full length of your rope or maybe use the extra attachment to switch to a double ended lanyard system. I've never seen one used so I would love to hear of the intended purpose or others from someone who might know. Also, how small of a line can be found to fashion one without being bulky/in the way. I believe you can see a picture of one in Strasser's Sherrill ad.
 
its used to clip your krab to when cinching your line rather than clipping the krab back onto the line itself and cross loading it. never used it myself so not sure what cordage they recommend
 
I know Sherrill has some "ultra-tech" type cord that works good. Its what I use. 5mm with a 4000lb MBS which is sufficient when doubled as in a prussic loop.

That's a nifty use of the mini-prussik. I'm not clear though on what's the advantage over simply cinching the branch with the lanyard through the biner to make the SRT lanyard. I can see there's less bend in the lanyard at the cinch, anything else?

you get double the amount of line to use...
-if you have a 15 foot lanyard then you can switch it to a 15 foot SRT system
- as a lanyard, it is only good for 7.5 feet

attachment points change...
-you can switch to a front attachment and work just like pictured above


I have been using this system for about a year and a half, and i don't know how i lived without it!!! i use it every climb(almost) one of the other benefits if that you can use the small prussiks to help stow your lanyard when not in use. I have 3 of them on my 20 foot lanyard, and when stowed nothing hangs below my knees (say goodbye to daisy chaining or knots)

I will try to get a pic tomarrow

Wow, that was cool. I'm enlightened. Thanks for the redirect TL. I am excited to try it out with some 7mm cord I have on hand until the good stuff arrives. I appreciate the simplicity of the timber hitch idea yet now that I've opened to the idea of carrying the mini prussik along I am thinking that the lanyard is as good a place as any to keep it. Maybe it will be like the great Camel back controversy where you dont realize how much you need it until you're staring it in the face everyday. I could see using it with a micro pulley to compound tail pulling ease when returning from sub horizontal stretches, or to put a handle on a loaded rigging line to dance a load through branches below, a quick "sheathed" pole saw hanger, squirrel snare...I also like Wizzard's daisy chain solution for stowing the 20+ ft lanyard that I would use more if it would mind itself every once in a while. Thanks for the help y'all.

the way that your Biner/rope snap interfaces with the limb/trunk is the biggest issue. Carabiners and snaps are designed to be loaded in a specific way, and they tend to cross load when cinched up on a limb. Another issue is that anytime a piece of hardware that has moving parts(even if they are locking parts) comes into contact with an object that it was not designed to, there is a chance of failure... an example of this would be: if you imagine Moss's pic above, but you attach the biner back to the line, there is a chance that certin movements could cause the twistlock mechinisim to open... same idea with a rope snap.

Look at moss's pic.... notice the way that the Biner takes the load... could not ask for any better situation... no sharp bends, no bad contact on the Biner......
 
Yep, that answers my question too, thanks.

By the way, want to give credit where it's due, the lanyard photo I posted is by the same TLHamel, linked from the other thread mentioned above by TL.

RemovalWizard that looks like a great idea for a redirect but how about if it is used on a spar? It would have to be snugged up a bit more. Wouldn't the biner again have a load against it's gate as it tries to conform to the roundness of the tree?

The other advantage I could imagine would be that sometimes in awkward angles and you have to return back to the point where you have cinched around the tree, rather than having to unclip , you could slide the prusik towards you, and then unclip the carabiner. Not sure if this really saves that much effort, but it's an idea.

Great explanation and pics. I use the New England Ropes "Tech Cord" for this. It is 5mm which provides good grip and has a tensile of 5000#. Mark B showed me this idea a couple of years ago. I don't use it too often, but when I do it is really good to have.
