only a matter of time before they did this, i find the one handed method kinda shady, and he loaded the tibloc wrong. basically a grigri for small diameter ropes. it was first developed for fire bailout.

sort of, my understanding is that the cam and size are adapted for small diameter tech ropes.

Actually, it doesn't just hold the rope in place. If you look at even the 1st few seconds of video, you can see that rope goes through it then it is used as a pivot point to redirect the rope up and toward the other side of the device. You can then have the rope running through the same hand you are using to pull back the lever, freeing up the other hand to shoot shit with.

On the ascending bit. kind of funny how he explains that you can either use a sling for a foot loop or run the end of rope up through the tibloc biner for a pulley redirect, but fails to mention doing both together, which actually works really well if you have a sling to start with. But then again, he's not a Petzl guy.

Look at this picture from the Petzl webpage: [image]http://petzl.com/files/imagecache/product_outdoor_slideshow_image/files/node_media/tibloc_corde.jpg[/image] -or you can read the instructions: http://petzl.com/...%20B01500-020799.pdf
hmm odd, you are right, I must have had an older instruction version or something.

The cam itself isnīt modified (at least as far as I could tell by just eyeballing one), the main difference is the pin which holds the rope into the cam which you can see to the left of the outgoing rope. This forces the rope to contact the cam considerably more than in the standard version and itself provides quite a lot of friction.
Developed by some guy in the NYC Fire Service if I remember correctly.

I've rapped with an 8mm rope and grigri before. It locks up but not quite as quickly. Once locked, it's just as positive as with a larger rope.
It's not necessary to change the cam, just throw in a couple friction points.
Am I looking at this correctly? You can't open the grigri? So to reload it you'd have to pull the rope back through then coil it back into the bag?
I guess this kit probably costs $300 or so, in perspective of just how much the military spends I guess these could be considered disposable.

he never showed how to load the device. but the photo upthread shows a pretty normal looking grigri with the addition of the u-bolt. i imagine you could have the u-bolt attached to just the opening plate of the device without having to go all the way through both sides, allowing you to load it like normal.

The pin on the cam means you have to thread the rope through but I guess those guys are strong enough to manage this, according to Petzl it is a one-time use object anyway!
$300 probably doesnīt buy the bag! Retail in Europe is $450 or so.
Why do those guys wear all black stuff when they are going down a white concrete building in broad daylight?

Guess it depends on your interpretation of the English language!
"This system must be immediately retired after it has
been used for a real escape, or when it is determined
to be no longer safe for use."
The first clause of the sentence says it is single use, the second says if it is no longer safe. The first clause (the dependent clause) has been seperated from the second (the independent clause) by a comma. If Petzl want to say the item can be used after more than one use but if undamaged they should replace the comma and the `orī with `andī.

Its not about INTERPRETATION, its about understanding the different systems this device is used for. There is the EXO tactical and the EXO escape.
The EXO was first developed by the NYFD & Petzl as a means for a quickly deployable emergency escape system out of burning buildings. It comes pre-rigged in a bag with a massive hook at the end for use against a window ledge. The whole thing sits prerigged on a harness, in a bag, to be deployed last second. Its also on some SUPER heat resistant cord.
There is also the tactical. Exact same device (the descender part) as the escape, just with a different use in mind, so the rope and attachment system it comes w/ is different. No need for the massive price tag associated with the heat resistant rope. My understanding is that "escape" refers to use in an emergent fire situation where the rappel may be done quickly. Otherwise you can use it many times in a tactical situation. At least that's my understanding.

But if you read on they talk about it used in training.
This item is not used once for training and then disposed of. I wonder why it's good to reuse for training yet not in a real escape. Must be they don't want you using a burnt rope again!
Fact of the matter is it is a reusable/ repackagable item.

Iīll give you that one!
The link above and when I search gets me into the Petzl home website where they only discuss the Exo Escape system which is as I described. But on Petzl USA there is the Tactical which as you say is re-usable .
The rope appears to be the same, 7,5mm Technora but with a different attatchment.
Still donīt know why they wear black on a sunny day though!
