Footlocker/ Rock Exotica Dualascender?0

[rumination]

I was just thinking I might email Petzl and ask them that!

Here is a picture of the Shunt used with a doubled Fly line.

Does the shunt slide smoothly as the footlocker does? It would seem that as you use the larger ropes that it can accomodate, that you would begin to cause internal friction which might not alllow it to move effortlessly, thus you might as well be using a prusik

I sent an email through the Petzl website. I'll let you guys know if I get any response.

I doubt the Shunt works as smooth as the Footlocker even on 3/8” line. I have never used a footlocker but if the Microcender used as a lanyard adjuster is an indicator, the footlocker should be effortless. I bought a Shunt to footlock with because I didn’t like the hassle of installing the Microcender on a single entry line.

Guys! When are arbos going to start to believe the manufacturing engineers when they have a rope size for the gear? There are good reasons for setting those sizes.

Using tools for techniques that the engineers didn't count on can lead to problems too. Using a Shunt as a lanyard adjuster falls into this category. There are other much better tools, rope and mechanical, that fit the bill.

The Shunt WAS designed to be used in the footlock. Why not build one that works on 1/2"?

Tim.

Not directed at you

Arbos are just about the only ones in the vertical rope world who use half inch/13+mm rope. It wouldn't make sense to engineer a tool that would only sell an handful.

I'll try to post pics of the ISC device.

Thanks Tom. Point taken. I forgot about the money. But if they would have done a little more research before deciding to put the item into production, they could have designed the original to accommodate lines up to 1/2". The same product would then be purchased by more people thus making them more money.

For some reason AS isn't liking me today. I got locked out this morning. Now I can't post pics. Did I say something wrong?

The Shunt has been out for years. It's only been lately that arbos have discovered it's uses.

This might be a pretty large image. In the interest of getting the pic up, I just took them off my camera.

Point taken, Tom. You are right.

 

[Tim Gardner]

Nice Tom. Why the need to adjust between the Mongoose and Footlocker?

Are you worried about something spinning that knob off?

 

[Tom Dunlap]

The adjuster is a system that I copied from "On Rope". It allows anyone to use the ascender and have the bridge the right length. This is critical if climbers want to have shoulders that function when they get older.

This is a prototype, like I said. When I got it the bolt had a Nylok nut on it. In order to change ropes I needed to pack along wrenches. I replaced the Nylok with a grade 8 fine thread bolt and the knob. I tighten it down firmly and it doesn't move. When this goes into production there will be a spring pin similar to what is stock on the Gibbs.

I just heard that mechanical ascenders are not allowed to be used in the aerial rescue at the TCC, or at least it wasn't allowed two years ago in the MWTCC, This seems screwy as i heard Dan Kraus used a Mar Bar upper in his aerial rescue this year. i'm trying to come up w/ my plan, but small inconsistencies w/ what is allowed from chapter to chapter are really throwing my journey off coarse. ARGGHHHH! [/B]

In last years Australian Nationals we were allowed to use assenders for the aerial rescue provided that they had a smooth cam. Makes sense to be able to use them as the comp is about simulating real life climbing conditions, so if an assender is safe and speeds your rescue up why should'nt we be allowed to use them ?

Proarbor,
thanks, this is what i want to hear. I think its screwy. apparently 2yrs ago a guy wanted to use his pantin, and it wasn't allowed. they told him no mech. ascender except in the mC. It's not in the rule book either way so i'm not sure i have a great arguement; i can gaurantee i'm gonna try though.

 

[Proarbor]

I think it all depends on your head judge on the day. Anything that is'nt clear in the rules is very arguable, I got a re-run at the AR in this years state comp after arguing an un-supported disqualification. Good luck anyway, climb hard and swing safe !

I got a reply from the USA Petzl distributor this morning. Pretty much exactly what I was expecting, but it was nice to get such a quick response.



Leon,
Unfortunately, there are no plans to expand the Shunt to fit larger
diameter ropes at this time._ Rock Exotica's Doublecender is the only
device that I know of that fits the bill._

Please let me know if you have any further questions regarding Petzl
products, and I will be sure to pass you comments along to product
development.

Best Regards,
Blane C. Todd

you can also set up the shunt like this

What kind of climbing line are you using there Stephen?
