If it locks up, simply raise your leg high high to unlock it. Of course you have to have the brake on.

How's that working out for you?

And also make your entire weight hang from your leg loop? You've obviously never seen me rap then.,...........or a lot of other people for that matter. I attache the prussik to my belay loop with a locking biner, so no leg loops involved.THat is not what the book shows. And that is my problem with it. I wouldn't have had a problem if the prusik is on the main line above the rap device and the cord is attached to the belay loop or tie ins. Good point, I will agree and say that I really have never understood the idea behind attaching your prussik to a leg loop. Can anyone enlighten me on the this one. P.S. I am too lazy to search
Well, if you have your friction knot below the rap device, you need to adjust the length of things so that the knot doesn't get sucked up into the device, causing it either to lock up or keep in a free sliding state. One method is to extend the attachment to the rap device out, so it's further from you; the other is to clip the knot to a leg loop. You may still need to extend the device.
So, basically it's a way of adjusting lengths, keeping things where you want them.
As said, leg loop + knot above device = bad.

I have a book that teaches the WRONG thing.., Thist thread is nothing more than a book review I give Knots & Ropes for climbers a 1/5
Uhh, I use this as shown and have for over ten years running with absolutely no issues. Never been able to screw it up yet. Very handy actually. I have no idea how you think this is unsafe, unusable, or even hard to search.
The only time I do not use it as shown is when I am rapping with a pig or two(big-heavy load), but we have little need to go there now. Good thing your rating of this literature means nothing.

Bob (X) -- you've been rigging a prussik above your ATC and fixing the prussik to your leg loop? I'm curious...given that the prussik as a rappel backup has been brought into serious question (it's hard to let go of a rope when you need it), and the inverting issue with affixing a suspension device to your leg loop...
Does "use...with no issues" mean that you'vee never had to rely on it...and it feeds nicely? Or does it mean that you don't invert when you loose control & the prussik locks up...or some other criteria?
?
