zigzag zag slipping

[caleb miller]

Anyone have this problem? It won't completely grab half the time, I just slowly slide down the rope,I have a new 11.7 mm rope and a used one both do the same thing it's the calomine rope

How old it the ZigZag? What model is it? Have you checked the functionality of its components? Is it full of sawdust or sap?

 

[caleb miller]

I will have to check the model, 1 year old, never abused, clean, no sap , all components move well

Well I would imagine a ZZ, like everything will wear and the gap will open.

 

[Brisbane Arborist]

True, it will wear but unlike say the uniscender it comes with a three year guarantee. You aren't using it for SRT, are you?

 

[caleb miller]

No not srt

A video of it slipping would be interesting.

Caleb, what friction saver are you using? Assuming that you ZZ is clean and all is working properly then possibly try using a pulley as your friction bend. Just humor me on this if you don't mind. I have a thought/theory based on to much friction up top.

I have owned 2 zigzags now. Both started slipping on poison ivy rope after about 1 year of hard use. I then went to the imori rope and slippage stopped but self tending was poor. In both cases slippage was greater when using a pulley. I just purchased the new improved zigzag version. I do not expect any difference in wear but I really like the zigzag.

Too much friction up top doesn't put enough load on the ZZ to make it grab correctly? Tell me if I'm right lol

Isn't the PI 11.7 and the imori 12mm? It only makes sense that it will start to slip as it gets worn.
3 solutions in my mind:
1 Get the fatter rope like deliminator did.
2 Use a cambium saver with more friction.
Interesting I found the caterpillar type had the most friction, more than say the leather.
3 Send it back for the warrenty if that is covered.
well, 4.........break it like some others have done, say bad things about it and get another new one and love it like so many of us do.

I think I understand your theory ML, the more weight you put on it the harder it grabs. It would be interesting if true. I suspect though that, like most ascenders, that increase in the progressive friction a descender adds because of pinch, squeeze or bend, is an almost constant percentage. So, even though it squeezes harder with more weigh, it has more weight to suspend.

So its like a "6 of one, or half a dozen of the other" type of situation? Same difference on the amount of friction the device applies vs weight the device sees?

That's my theory Richard, not sure it holds water though. Although I have to agree with if your think it's bad then stop using it, it ain't worth it.

Anyone know about coverage under warranty?

 

[Brisbane Arborist]

Anyone know about coverage under warranty?

Yes, it has a three year warranty. The one exception is for the original model which has been recalled, so time shouldn't be an issue there, and for cracking in the second model which Petzl are guaranteeing against for ten years. The third (2015) model has thicker side plates that aren't supposed to crack anyway.

With more and more time on one you get so good at finessing between the full stop and free fall. You also get better and better at keeping your hand away from any rope burn. I have owned 4 and 2 were returned. Never had an ounce of slippage (or shrinkage lol) ever never.

 

[caleb miller]

It has become a hazard at this point and sherrill tree only wants me to buy a bigger rope, wich would be ok if the advertisement said buy a bigger rope after 8 months of Gentle use

 

[caleb miller]

Petzl has not returned my email

I climb on 11 mm Velocity since the piece was invented and never a slip with 4 units. Not saying you are making this up but never heard anyone say such on any forum for years. No need to even tension it to get it to lock in my experience, it can just lay slack and if I fell....boom it is right there with a hold.

Maybe this is why you are getting no help, because you are such an unusual case.

I've read of more than one Climber complaining of slip within a year of use. I don't know about protocol here when it comes to mentioning other forums but it was on a UK forum where they talk about arboriculture.
