What about if it had the Orca ability? If it auto-locked you wouldn't have that problem, right?
As it is the rope does sit by the main axis near the inner spine, but if one side were to come out I'm not sure if the rope would slip out to the gate or not. This is just a sketch and I haven't ironed out all the details so please keep the comments coming. I don't like the idea of loading it gate heavy either, but maybe if I do switch it to an orca type lock it would not have the chance to slip out in the first place. Might make it a more universal tool as well.

Thanks again.

If I get Around to It I will weld some steel beiners together to try it out. I really like the orca lock idea too. So many possibilities! If I it was my choice I'd use steel.

Can you give me a link for that? All that comes up for me is golden retriever rescue and the like. I haven't been to my computer yet, so I'll also look when it get a chance. Thanks.


I like steel too. Thanks guys.
 
Evo if you weld 2 biners together thats half way there but what style would you choose?

If you look at the original sketch you might pick some sort of captive eye, double action maybe?

Side note:
Also an option take 2 solid biners weld there back bones together then take 2 swivels and slide 1 on each biner.
This would act as the top small whole still able to splice onto a loopie sling or what ever. Simple fix and it would keep it running true like the omni block.

Just an idea thrown out there. Or if you just run just a pair of biners you could use a nylon loop sling or a dead eye sling cow hitched on the top should be strong and can be at length from the trunk to be free to sway instead of a swivel top.
 
Not the same but if they're inline with 1 sling between the 2 off them the unit should still rotate as one and smoother than nothing.

I understand its different but it was the first example I could think of.
 
Why not?

How would they run?

They'd be paralell and uniform and run in equal symmetry. If one sling held the top of both swivels together and the 2 niners welded as 1 held the other 2 what would happen if not one even swivel motion?
 
Wow, I finally got a chance to sit down at my computer.

Thanks RopeShield, I wasn't having much luck finding the retriever on my own. It wouldn't come when I called....

KevinS, I am not understanding the way you would orient the swivels to work as one. The swivels attached to two separate biners would act like an egg beater, lock the two biners together and they would jam the swivels in place. Unless we are misunderstanding your layout, I think you would have to take it directly to a single swivel.

I'm really appreciating all of this brainstorming. I am really considering the change to the orca lock type of gate to capture both qualities. I don't know why I really like the one hand quick connect feature, but I think you could pretty much have the best of both worlds with the orca.

We will see.

Thanks again for the continued interest.
 
Let's see, if I were to make a proto type I would use the cheapest steel D shaped carabiners and weld the spines together. I'd probably just stop at that, or if I were feeling like putting some $ into it I would cut of the eye's of a shackle and weld that for the captive eye. I don't see much use for a swivel unless there were rollers to setup a MA like a fiddle block. I don't have a pair of warn out steel biners, but I'll look in the junk pile and see what I can come up with, it would be at least a few weeks before I could slap something together.

John, I would like to express that my interest in this concept is just fooling around, by no means do I plan on running too far with your idea.
 
That's cool evo. It's encouraging to see this kind of response to this double sided carabiner, I wasn't sure what kind of reception it would get. I have seen other product ideas met with more negative feedback and disinterest. So far, about 91% voted (Yes, Yes) with only one other vote and that's (Yes, No). All in all considered to be a worth while product.

And evo, I would love to hear from you if you get around to making one up. You are right you could get away with just the two carabiners, and simply attach the strap around the 'spines' opposite the load. You would get the basic feel for it, I would think.

Good going and thanks.
 
Really like this idea BTW John. There have been so many times climbing DdRT that my redirect had too much friction and this would've helped a lot. The rope wrench SRT has eliminated that issue, for the most part anyway, but I'm not to the point where I solely climb SRT. So do it, brother! I'll buy the first one. Hell, I may go fabricate a prototype out of tin foil and try it out tomorrow. Tell my wife I'll miss her.
 
Great idea John. I'd buy one. I'm sure DMM has their "Revolver" technology under patent, but if that were combined with your idea it would be a real fast running redirect. I use a couple of revolvers on each end of a webbing loop for a retrievable redirect for Ddrt, but I am pretty sure your idea could not be retrievable as such. Great idea, though, probably strong enough for a patent and then re-sell to DMM. Just a thought. :)
 
Thanks!

TreeLogic, All for the cause, all for the cause. Could you try making little tin foil revolvers to see if it would help you go faster...;)

Ward, I'm sure you're right about the revolvers. That would make a huge difference. One of my concerns is making it affordable. You see what one revolver does to a carabiners price. However, that's not to say that it wouldn't be worth it. The redirect on a doubled line is not just one extra point of friction and diverted movement...it is TWO. Having devoted, contained areas for each side of the line would make a huge difference, but I still don't know if one would still have enough trouble with the friction to make the revolver addition more essential.

PS - it snowed in PA. :confused:
 
what about this for the captive eye, take a regular bow shackle, one of appropriate size, and in the two openings (the smooth one and threaded one) first thread the 2 biners through, so that they are oriented back to back, where they then can be welded. The trick i guess would be finding a shackle that isnt too big but would allow the body of a carabiner to pass through, maybe would need to be bored out a little to make it bigger... but this would let you have both biners oriented along the spines where they then can be welded together, and if you really wanna get fancy, throwing a swivel on the shackle before the whole rig would make the thing function like an omni block. I know from a structural point of view you wouldnt WANT the steel biners rubbing against the steel of the shackle, but it would be a quick mockup of what you wanna do, or what if you even did this, and spliced an eye from an I&I prussik on each carabiner, then its just a matter of setting the prussik on a rope or girthed to a limb, and you are free to climb from there. It can work with all steel hardware, as well as with textiles.carabiners and shackle.webp

In here you can see the two biners back to back, the red line just meaning they are welded as one unit, and above is a shackle, only qualm would be a shackle with eyes in it that will allow the diameter of a carabiner to pass through. and the orientation of the gates seem backwards, but thats just asthetics on what i drew up
 
TL, that's what I thought too. I kept thinking I would see it in a catalog or online somewhere, as I thought it was sure to be out there somewhere. But, in all the four years that I've been looking I haven't seen anything quite like it.

I'm really thankful for all of you giving me this input and motivating me further to really work this thing out. I could have done it more clandestine, but without this encouraging response... I don't know how long it would have taken me to go through with it.

And Steve, if I get around to welding one up, I would weld the captive eye at the same time I joined the biners. I just think if you are going to be welding anyway... But your suggestion is very clever and I like the way you think. Great stuff.

Thanks a lot!
