Show us your home-brew Petzl Connect-Adjust (or other) setup

I'd think the strength would be limited by the eye.

The eye is like a loop, those break at 150-160% of the ropes strength.

The video is only testing one part of the Class I Double Braid splice. That crossover, in a regular splice, is being compressed by the cover, as well as sitting next to additional core, further expanding the cover, increasing compression.

How is an eye tested if they can't be ringloaded? Or is it fine with X type of splice? 

Why ring load test, it’s not used like that?  Typically pulled end to end, more like real use.  A Class I Double Braid splice requires both the cover and core to work together, Class II usually just relies on the core for the strength.  Their splices are designed accordingly.

I thought you meant the loops of a spliced eye would reach 160% but I see now you must have meant a spliced eye would be similar to a loop (which is what i thought. 

Go into the comments of the vid there is a good comment left by a samson employee regarding splicing and when it breaks in the taper vs breaking in the eye. 

FWIW, I meant testing the line strength, in isolation, with no splice... Literally just one piece of cord, slid up the inside of another, with both ends wrapped on large diameter bollards. Not really a practical test -- just curious about what happens to the line strength that way.

Right, that is what my post addressed, I think it will break at it’s rated break strength, not double.

Bit of a thread grave dig, but i’m stoked on my new setup. These are Amazon knock offs of the connect clamp. Nearly identical to the petzls. Allegedly rated to 9kn. Using 8.5mm beal opera, cloved to a petzl cock ring. Super smooth releasing. Probably going to put some cord through the eyes.

My 8.1mm Ice Line that I've been using on my modified connect adjust needed replaced. I had this 6mm Imlay Canyon Gear pull cord laying around and decided to try it. It's working great so far in tests hanging from a squat rack. Haven't taken it outside yet to test for real. I decided to reinforce the tie in loop with some webbing I had laying around because my old cord saw a lot of abrasion there.

Copied the idea from Tanner Wanish who posted about it elsewhere but I've adopted the Maxim 5.5mm 5mm Tech Cord + Petzl Connect Adjust metal piece combo. Tied with a fig 8 on one end and a barrel knot as a stopper on the other. 

Hasn't slipped once, super low bulk and weighs next to nothing. An added plus is the concerned looks I get from people when I use it. I've now replaced my adjustable tethers for aid climbing with the above setup as well.

Just FYI, Imlay pull cord isn't super strong. It's fully polyester, so it's essentially totally static, and its breaking strength is ~9.5kn without knots. Probably fine for an aid daisy, but maybe not great as a sole connection point, IMHO.

Asking to clarify, are you saying you use a single strand of 5.5mm cord as your personal life supporting tether?

And just incase I may have misread, you’re also saying that other people being concerned for your life is a bonus of using the aforementioned critical life safety system?

Thanks for the heads up on that. I thought that I had remembered it closer 12kn, but just looked at their website and it appears you're correct. It was a decent proof for me that cord this small can work, but I'll probably buy something stronger now.

I'm not usually the paranoid one about gear but I agree that using sub 7mm cord gives me the willies for a singular connection point, no matter what it's rated to. Something about the nonlinear relationship of diameter to abrasion resistance makes the weight savings not worth it I guess.

Have you never experienced the sheer joy of screwing with the minders of other people's business?

9kn is fine for bodyweight.

But any fall on it could provide results much different than expected out of something like this, look at some of how not 2’s drop tower tests and a tiny fall can explode static lines with ease :/

Simply don't ever put yourself in a position where you can take a factor 2 fall onto your static tether.  IE don't climb above your anchor while tethered.  If you don't do it, it's not a situation you need to worry about.

Find me a single report of a PAS failing. I've tried, they don't exist. Humans are essentially giant bags of water and diacipate force very well. People are taking high fall factor whips onto adjusts of various cord diameters while aid climbing(see Oliver tipets vids) 

As you mentioned hownot2

Hey Alex, yes that’s correct. The Maxim tech cord is rated to 4700lbs (21kn) and the technora core and polyester sheath makes it extremely abrasion resistant. It’s actually a chore in itself to cut the cord even with scissors which is nice to see. I understand the optics can be unsettling but I can’t justify something thicker just because it seems weird when the numbers dictate otherwise

LOL everyone got triggered all at once
