backing up a floating false crotch

I know that some of you are climbing with a floating false crotch or an Adjustable false crotch or the secret weapon, whichever name you are using, I may not have it correct.
What do you use to back up this system once you've reached your desired height footlocking, before you 'transfer' to your doubled rope to go to work.

And, is there a way to backup this system that would be retrievable from the ground.

I believe this may have gone around on at least one occasion, but I'm having troubles locating it.

Any thoughts,

Thanks, Russell.
 
Well you can use single line if you want to make it retrievable from the ground. That's the only retrievable way I'm familiar with but you bascially foot lock up and then tie a stopper knot and clip a carbiner in it below your knot so if the prussik fails and slips it will only go down as far as the stopper knot with the carabiner.

Yup, that's the way.

If you want your groundies to be able to lower you out of the tree ICE, than you go up into the tree in the short end of the rope. The long end of the rope is secured to the tree through a figure eight. Secured of course by tying it off in a correct way

The anchor system for my SRT line was made by Nick. 3/8" coated Yalex with nylon eyes in both ends. There is enough to go around a 6' diameter tree. The prusik is made with a tight eye for the biner and a longer eye so that I can make three wraps.

My preferance is to use a rack for the belay. There is lots of friction and the rope tails up so that the belayer naturally adds more friction by pulling the bars together.

If a figure eight is used it should be a large rescue eight with ears and a double wrap should be used. Figure eights don't develop a lot of friction. In most setups a Munter hitch develops more friction than a figure eight.

Lately I've been working in tall trees so I've taken to tieing two ropes together so that I can be lowered in case of emergency.

Floating False Crotch is correct. Some of the Europeans call it a 'Floating Anchor'.

An Adjustable False Crotch is something like an Adjustable Friction Saver or a Rope Guide.

The Secret Weapon is one type of Floating False Crotch.

should the carabiner on a stopper knot be double locking or does it not matter?

Don't even think of taking others than triple action biners up into the tree Jumbo. The biner on my handsaw scabbard is a red screw biner, all the others are triple's.

What's the point in getting your climbing gear mixed up with non climbing gear?
 
I agree with you on not mixing gear and not bringing up any hardware that could be used accidentally in an unsafe manner. I quess the question is based more on the fact that it is not a load bearing link in the system. It's a backup for the knot.
 
I think you could even use a twig, the knot can't slip anymore. But if the twig would break or slip out of the knot.

It's not that much of an issue to me because I make a knot in the rope and attach the end of my footlock prussic onto it. On the end is a triple lock biner.

Triple lock or double lock? A double-locking 'biner = a triple-action biner. Think of this progression:

--non-locking 'biners ( = single-action): push the gate and they open; no locking mechanism, but one action is required to open the gate

--single-locking 'biners (= double-action): twist lock, screw lock; one locking mechanism thus two actions are required to open the gate (one action to unlock the gate and one more action to open the gate)

--double-locking 'biners ( = triple-action): ball lock, push and twist lock; two locking mechanisms, thus three actions are required to open the gate (two actions to unlock the gate and one more action to open the gate).

At the ITCC we have been requiring a double auto-locking 'biner for this application for several years.

ANSI doesn't address the issue. I don't know about the Euro standards.
