I made a rigging ring n ring a couple of years ago out of 3/4" tenex and a couple of shackles for a 3/4" stable braid. we used it to pick a tree off a car a Mercedes dealership.

I used large washers to center the shackles and rubber bands to tighten the eye up. I quit using it because it was heavy to install and took a really large crotch. It really limited the usability. These look very easy to install, I might have to buy some of these rings.

Is that All Gear 1/2" Bull Line?

What is the overall length, end to end?

Close but not quite. Its samson 1/2" stable braid.

Dont get me wrong all gear is good rope, I used stable braid and like it. The biggest selling point in my mind is samson rates their rope products to SWL of 20% (5:1). Not saying I will use it to that constantly but they are confident in their product so that I can be.
The overall length turned out to be 4'1" pretty respectable for I+I double braid. I might have been able to get another 4-6 inches but it would have been tight.
X got thinking about what you said about the rope always breaking and no rings have. Its probably because the ring gets so much support from the rope. The rope has to break to allow the ring to deform enough to break.
I cant wait to try this. Hopefully this week.

X, when your slings were breaking where did they break? The eye, the throat, the taper or elsewhere? Thanks for offering these rings seperate.

In work use, place the catch thimble between the rings, this will keep it in check and not be able to bind on the rope. But I'm not sure about the thickness, it might get bashed pretty good if it's that thick.
I need to look up the company i bought a whole bunch of very thin D rings. They've been great.
That thimble might work great though, you don't know till you try it.
I've just noticed that if the object is placed outside the rings, it can bind if close to the ropes diameter.
a brass snap with that same shape as that thimble doesn't seem to bind though, so your thimble might be a great shape for that use.

Look up stainless steel o-rings or just rings, they come in lots of diameters and sizes, you can work down to 0.5mm on these rings, I buy 100's and never had issues from customers. I use 4mm x 36mm for my pulley saver recovery setup.

Looks good, nick! I'm gonna have to build me one just like it!
Love the widened retrieval thimble. Smart thinking!

I used mine today too. It was great. I didnt have to carry a heavy block up for the super light rigging we were doing. Set it mid tree, and worked down rigging dead wood off. And I didnt have to go fetch it at the end. Retrieved like a charm. Worth every penny of the 50 bucks or so I got into it. Thanks X.

On all the slings except the loop ones, they all break at the taper inside.
When tied or choked, they break at the choking part of course.
The loop ones have cross overs (if that's the right word, I'm not a splicer), so the main loop is very thick and strong, the weak point is the single thickness around the ring, those break at the ring.
NOTHING we offer breaks at the splice. Which is the way a professional splice should be.
I wanted to find pictures of the breaks and post them here.
good question, btw.
I broke many at my own house using our 40,000 lb hooklift, just to see where they would break. Couldn't break in basket form though, dragged our crane/hooklift truck across the ground.
Then, independent testing in New York, all the slings we offer broke the same. We took video and pictures.
I'll post pics here, next.

same type of sling, but the green one. attempted to break in basket form.
to simulate a block in the big eye, i put in a loose ring.
amazing.... it doesn't even fall out under load, imagine that.
anyway, the 5/8" amsteel blue used as the rigging rope through both rings broke at a bit over 35,000 lbs. The sling wouldn't break.
the tester said there is no need to break it, it's going to be around double the other ones we already broke, 60,000 lbs.
the amsteel was used on the other slings, so I wrote "used" on the paper.
The testing was taking a long time and I know that basket is double anyway, so we moved on.

the 3/4" stable braid.
Good golly that thing stretched and stretched and stretched.
That's a big reason why i want tenex to be most of the slings. I don't think the rigging point should be elongating in the system. Of course, at only 10% of the breaking point, you don't see too much stretch if you're working with that %.

X. Thanks for the answer, it was much more than I xpected. I wonder how much using the amsteel on prior breaks had to do with it breaking on the double ring setup. Thanks for sharing the break test and pictures. Very interesting.
I brought with me about 30 or 40 feet of new 5/8" amsteel blue to the test to use through the rings. Cut about 8 to 10 foot lengths, tied bowlines in the ends (reduced it 55%) but then put it in basket form to bring the numbers back up.
So, it wasn't the same piece for every test, but that choked green sling test, the amsteel piece was used at least once. I'm sure it had to be weakened.
See how high the breaking numbers were on the tenex tec? 30,000 lbs for straight pulls. That is because Samson does more vigorous testing for their numbers, they cycle it many times to simulate work use; what comes to my head is 50 times at various strength percents....
Anyway, that's why we went with Samson's numbers and not these huge numbers. A completely new sling has so much more strength.

My thoughts exactly, Samson makes some great products. Normally for my splicing projects such as with the rings i go with Samson double braid or tenex. Thanks again
