I'm looking for a perfect ring shaped Carib or Maillon that will allow me to rotate and therefore release attached cords which are under tension. It has to be climbing rated.

Does such a thing exist?

I've never seen one, and I doubt it exists from a safety point of view,
It's be far more likely to deform under extreme load and fail.

I thought that may be the case - any ideas for an alternative solution. I'm looking for a failsafe to stop the whoopies on my hammock hanging experiment getting into a "locked" situation, May just have to be a loop in there somewhere that I'm willing to cut if it comes down to it. A climbing rated turnbuckle would do the trick if such a thing exists?

Are you using a marlin hitch on your tree tapes if using them?

Good question. I want a horizontal SRL (direct to both trees) pulled as tight as possible so I need a release mechanism.

I have two hanging options at the moment.

Option 1: I have some custom 2" 3m webbing strap with Caribs (or this could be a marlin spike) - using the caribs I wouldn't be able to undo these.
Option 2: I use the DD straps like belts tight on the tree with a standard shoelace knot then maillon or softshackle to these - hoping that the webbing will come loose when the free ends are pulled (even under tension)

Both options worry me a little so for my first hang I was going to build in a little safety and use some 550 looped 5 times in between one of the straps and the whoopies until I see if it will all release nicely. However I would prefer a bombproof method.

You suggesting that using the marlin hitch I could just push the dowel free?

What you using as the toggles then? I take it as it's the knot taking the weight, not the toggle it doesn't have to be anything to OTT?

Not sure if I've got anything like that - I need something tapered and smooth. Don't forget my rig will always be under tension so being able to pull/push it out easily will be even more important.

I reckon a stick would be crimped by the hitch dude and therefore not be able to pull out. could top get a length of steel rod from b and q? I used Ali as that's what I had lying around(benefits of working on aircraft for a while) just to make you feel better I'm typing this while in my hammock! In the garden.

with a set up like that why don't you just have tight ridge line and then tie the hammock on with prussik/klamhiest.

I don't trust prussiks on amsteel, prussiks work better on lines of different diameters and amsteel has a low melting point, although I haven't tried it - but I'm belt and braces.
