Zigzag questions

[Alcoley]

Just picked up a new zigzag from vermeer. Can I run an unspliced eyed client line with it? What's the best size line? Thanks

 

[Mowerr]

Yes you can. Much like the hitch climber system, you just need to use the right termination knot so the knot doesn't touch the links.
I use an anchor hitch and I just tuck the tail on the far side of the carabiner so the bridge and tail of the anchor bend is away from the links and like the hitch climber system...the knot won't mess with the function of the links.

 

[Alcoley]

Ok thanks. I've got a new line and didn't want to spend the extra 200 on a new one. I probably will anyway in the near future.

As far as the correlation between diameter of rope and the function of the zz... The thinner the line =less friction. I think petzl recommends between 11.5mm to 13mm. Another thing to think on is the construction type of the rope which effects the function of the zz too. So a smoother tighter cover like a kernmantle or 24 strand is less friction than 16 or 12 strand.

I use a 5/16" twist shackle on top of the ZZ to avoid interference.

I wound a split ring through the shackle and the hole in the pin to ensure it doesn't work loose.

I like the idea but technically it's not a rated piece....I would climb with it though.

 

[Winchman]

You can pay a lot more for a Wichard, but I doubt it's rated either.

Wichard Locking Twist Clevis

This stainless steel shackle from Wichard is often used to attach a flipline adjuster. It holds the adjuster in a position that is easier to access. It has a variety of other potential uses f

I've got it backed up with a loop of leftover RIT prussik cord just in case.

I've used the same twist clevis on non-spliced ropes (wire/threadlock the pin for safety) with my ZigZag as well and found it... OK. It does eliminate the issue of a biner and/or knot interfering with the links which is of course crucial, but it does add weight, bulk and length to the system which makes it a little less slick than the original/intended configuration.

 

[Mowerr]

Yeah the wichards aren't rated for life support too but to each their own...both my zz and hc systems do great with the anchor for termination.

 

[Alcoley]

Finally climbed on the zigzag today. What a dream!!! I love it. 10⁰0000 time better than the Blake.

 

[Winchman]

Is there any reason not to use the auxiliary hole on the Zigzag to get more clearance between the rope/carabiner and the friction chain?

The Petzl site says it's for adding a ZILLON lanyard or connecting a second system.

 

[Mowerr]

I can't see why not. I know I would do it but mine is from the version that came out just before that new one

Performance

Locking and descent control performance are the same in the two configurations.

Connector positioning

The connector will not be positioned as well as through the integrated sleeve in the ZIGZAG's rope end attachment hole. During use: verify that the connector is correctly positioned and interacting properly with your equipment.

Premature wear

The device is out of balance if the rope end is not connected to the intended location. The frame of the device tilts as the friction chain and the connection point to the harness tend to line up.

The rope rubs especially on the plastic part between the two side plates, accelerating wear on the device.

 

[Winchman]

Thanks for that. I didn't see it in any of the Petzl pdfs on their website Where did it come from?

Petzl's Tech Tips for the Zigzag

 

[treegongfu]

Ive been wondering if anyone uses two zigzags in a DSRT setup without the Chicane or a rope wrench? And what the consensus of that would be.

I assume that as long as you keep both ropes loaded you the forces should be equivalent to those generated by the approved DRT

Any opinions?

 

[Crimsonking]

It would load the devices in a way that they weren’t designed to carry the load. I just can’t think of why someone would want/need to do this. There are so many options that fit the device’s parameters- why go looking for something beyond its intended use? Instead of two srt lines, why not use the extra hole in the updated zigzags and set up a v-rig system. Beautiful setup when it’s needed. Or use two ddrt setups.

Would you climb with two hitches on srt without wrenches or the like?

 

[Burrapeg]

I have been experimenting with climbing with two SRT systems in place with my two ZZ, but this was with a DIY wrench above each ZZ. It is hard to keep both systems loaded equally at the same time as I climb so I think the wrenches are still needed. And I am on just one system each time I shift the TIP of the other system up higher.

 

[treegongfu]

That is what i thought. The zigzag is such a pleasure to climb with and adding a wrench above it allows for SRT but also has some disadvantages.

Thus my interest.

I made this link earlier today to get more clearance around the ZZ release.

It frees up the space between the release lever and the rope...

that's normally taken up by the carabiner and knot.

I could have made it 1/2" shorter, but I wasn't sure how easily it would move in the body of the ZZ with a load on it. I've got my full weight on it in both pictures, but I haven't climbed with it yet. The spacer on the lower end gets the rope in line with the body of the ZZ to prevent twisting/side loading.

According to my calculations, the swl is double that of the ZZ itself and it only sees half the applied load. It's serious overkill, but I wanted to use aluminum from a trusted source that I had in the shop.
