I was wondering if anyone has ever thought about making a foot locking prussik that could be used to potentially tie a double klemhiest in order to back up the kong dual ascenders. This would be like a flp with an extra loop at the top. Then you'd wrap each of the larger loops around separate legs of the rope and pass the tight eye of the other end through the two loops and then down to your saddle. If anyone has tried this please give me some feed back as I am working on the construction of the piece in order to tie this knot and try it out as a back up.
Double klemheist backing up kongs

i usually climb on the Kong Dbl Ascender on a single line; favouring a Distel as a backup; because both legs serve off 1 side.
i'll drop a sling from the base of the ascender to the right foot; and have Pantin on the Left foot. So, i have both legs as independent power; and the chinp effect. i like the 2 hand grip to keep the body more inline/ less leveraged without a chest ascender. If the bod falls away from the rope, the CG is then at an angle; therefore leveraged, so then it takes sum of the effort to get inline or more effort to lift the leveraged load; just as anything else.
That avatar is something else.

It seem like Klemhiests would work. You would want to test it thoroughly though, I wonder about the length of the down loop, the one the long leg passes through. Would the ascender loosen that too much and keep it from catching in the event of a failure?
I use tautlines for doubled ascenders. My backup cord goes all the way back to my harness tie, bypassing the ascenders so it's just a single 9' line. I couldn't efficiently tie Klems with it. This is an older picture with 6mm cord, I changed to 8mm.

why wouldn't you just attack the purple rope to the top of the ascenders?

It wouldn't back up the tether or the shackle. Most guys do just attach them to the ascenders but I like it this way better.

If you attach them to your ascender its parallel. If you attach them to your harness its in series. Correct me if I have it backwards. I have it attached to my ascender as of now but I am looking to attach it to my harness for the added safety. I’ve found that Klemhiest don’t always grab. I’ve gone to using a prusik because I feel it’s a little bit safer it is little tight to undo if you sit in it or load it up a little bit, but if your using it as a back up that shouldn’t be a problem. You can tie a single line prusik, so you might be able to apply your theory from above to the prusik.
It would seem that a klemheist would bite in this use depending on the diameter of cord compared to the diameter of rope you are using. I would test this thoroughly before I used it. although seems to me that it may be difficult to tie in this use. I was using a blakes hitch tied with a 5mm cord(rated at 5000lbs) attached to the top of my kongs but have discovered that it is easier to use the tautline instead.The tautline hitch can be easily tied with one hand so you can tie both sides at the same time and I have been attaching this to the top of my kongs with a screw link but I like the idea of joining it with the tether for added security.

Mahk has (or had) a backup system made of 3/8" hollow braid that independently backed up each line while using a double ascender. It was a simple idea, a locking brummel eye with both legs long enough to tie hitches onto the static line.

Mahk- that looks like a standard locking brummel. Right? If you load that the wrong way, the thing could slip a bit...but only enough to take up the excess slack in the eye.
If you do a third pass, it become unslippable.
There are a ton of ways to do this back up. Here's mine...

I use a petzl chest ascender under the double ascender attached to the tether with rated screw links. That is the back up for single line... For double line I back up the second line with my regular climbing hitch and biners, keeping the hitch above the ascenders and clipping the biner through one of the handles... The Kong advances the friction hitch with negligible added friction. Everything just snaps in place then unsnaps, and the climbing hitch is right where it is needed to get to work... no fuss, no extra gear..
This is well within my own personal safety margins, though technically, the manufacturer, Kong, does not approve of clipping the biner through a handle, so I've been told the system couldn't be used at a strict TCC... Guess I'll have to make it to the Masters Challenge one of these years to find out for sure...

nick i really like that setup. how much would you charge for something like? i have a few other splicing questions if you could send me a pm that would be great

hi everybody
I'm stefano ( senprebene) I change my login name
in Italy a lot of people start to use instead of the knots for back upping double ascenders a device call LIFT from a company CAMP ITALY
in another post we talk about that
is very light ,confortable and more fast that a knot in the ascending action
this is my opinion

Here is a link. I have seen this on Mr. Storricks site before. It looks kind of cool.
