Another mk2 zig zag fail

[peatff]

Excuse my ignorance but we're are the cracks

 

They all seem to go in similar spot.

It would be interesting to put a cracked one on a force gauge to see how much pressure/weight would cause it to fail

 

It has failed already, that's why it has a crack in it.

Think he means become ineffective at holding the rope and therefore causing the climber to fall uncontrolled.

I'm sure someone tried that and the spliced eye of the rope still failed first before the cracked link of the zz did.

That's my understanding too Mr Git...climbed on my cracked ZZ2 until my Mk3 arrived.

Yup this was my point, at what amount of cracking is there an actual danger of a fall

[treequip]

My main concern would be that if it deformed or broke any further, any open ends could rag the rope. It seems that Petzl are happy enough that this wont be the case.

[silky fox]

Also my concern in the extreme...i am happy that it grabs the rope sufficiently even with cracks but sharp edges on the fibres would be my only concern

I've got a single crack in mine, haven't got round to sending it off but am not worried. The only time the zig zag freaks me out is if I get it caught on a branch and it flexes the "wrong" way if that makes sense. I know in my head it won't break but it's a bit disconcerting!

I know for a fact that Lyon equipment did some extensive testingnon extremely damaged zigzags and found them to still operate within acceptable parameters. Lyon are the UK petzl distributors and are much more than wholesaler, they make and test a lot of rope access equipment.

 

I'm only mentioning this to hopefully put some people's mind at rest. If you do find a crack in either a zigzag or zillon then advice is to retire it immediately and speak to your supplier. There will be no issue in getting it replaced for the latest version which has none of these issues.

Thanks for the response Mark....i just sold my Spiderjack because i am so happy with the ZigZag....shame it had the hic-cups....but it bothers me not. Awsome device!
