Adjustable Prusik

[tod_k]

Been using this a ton. It comes in real handy when you get to the top of your acsent. You can take a bite and slide the hitch up close to your anchor, makes getting into a work position much easier.

That's a pretty neat idea. Do you basically use it like a flipline?

Flipline? I use one like that (with Schwabish)just to get closer to my tie in point.

It's an ascending prusik with an adjustable bridge. Nice, TK.

 

[tod_k]

Nick, just to get closer to the tie in point while footlocking.

Nice idea Tod, haven't seen that one before.
If only I could get more work in trees that make
it worth the effort to set up the footlock system.

[NickfromWI]

AH-HAH! Now I get it. I was wondering exactly where you use it.

I might have to make me one of those!

Oskar, it is a very usfull tool but not my idea. I saw Bedes I think last year use one during the Masters in Montreal. Although I do not know how he set his up but I sure its better.

Attached is a graphic of a true adjustable prusik, called a Purcell Prusik, which is made from a single length of cord.

Rescueman, though your system is less gear intensive, it only offers a 1/2 of the adjustability...let me explain.

The prusik loop is just that...a loop. If the whole works is 3 feet long when at it's longest, it can only be 1.5' long when at it's shortest.

Tod's version can be cinched up to almost nothing.

I like it. I am thinking that is what I can use my footlocker for. I like using a prusik loop for footlocking and hate to have a piece of gear on the truck that I never use.

Thanks for the idea

Tod, I don't fully understand how you use this thing....would you mind spelling it out for those of us a little slow on the uptake??

 

[glens]

It's just a two-stage rig. The whole thing is used on the main rope. When its friction hitch reaches its limit, there's still the second one available to advance on the first. It's a good idea; I've been taking the time to stick a short one in place as needed.

Thanks glens, Cory does that make sense?

 

[Brock2saws]

It might to Cory, but it doesn't to me. I'm missing the whole point.

When you choose to footlock into the tree the ascending loop, the one tied onto the access line, is generally left long so that the climber can get a full bite everytime they footlock. There are times when the climber gets to the top of the rope but they're just a little shy of the tie in point. With TK's setup the climber can now move up that last little bit on the ascending loop. Instead of having a candy cane loop the climber will stay supported and reduce the possible fall.

On Rope 1 sells a similar setup called a "Quick Adjust Safety" I put one together and it is useful in certain applications.

 

[Brock2saws]

I get it. Thanks Tom.

You da man Tom

 

[cory]

Yeah, got it now, thanks guys.

This'd be my contribution to this thread: It's a 10mm FSE Footlock lanyard, with a ISC captive eye karabiner attached to it through the krab's eye with a cord made by New England called "Tech Cord" with a 5000 lbs. breaking strain acting as the adjuster, backed up by a shackle at the end of the lanyard that'll act as a stopper in cade the mini V.T. fails. You could also attach the shackle to the krab.
The adjusting is easy, meaning you can get closter to your TIP, in doing so reducing the risk of high fall factors - as mentioned before in this thread. I think as we use increasingly static materials in access lines (Dyneema, for example!) we should really keep an eye on this possibility! I know from observing my own climbing style, that there are situations in which I'm exposing myself to such situations, hence the idea with this adjustable lanyard.
