Just been climbing in France and I rather like their dynamic anchor setup made from a piece of dynamic rope. Does anyone know how to tie one with places for two carabiners? Can't seem to find any info online and obviously don't want to stuff it up.

( Its like this except with two crab instead of one - https://www.mountainproject.com/images/78/25/107277825_large_3ab67f.jpg )


Cheers

Take a length of dynamic rope, and tie whatever termination knots you prefer to use on the ends. Then thread one end through the usual tie-in point on your harness. Align ropes so parallel then tie both together in a figure of 8. You should now have a 2 arm lanyard securely tied into your harness. You can fine tune the lengths to suit.

The knots are a bit bulky and prone to wear, if you're going to use the lanyard a lot or on longer/harder routes then better off buying a purpose built one e.g http://www.beal-planet.com/en/35-longes

For permanent attachment I'd tie a length of rope into the harness with a rethreaded 8 or overhand so you have 2 tails. Attach krabs to the tails with barrel knots and trim the remaining tails for neatness. Clean, simple, pointless IMO.

To make them removable don't tie the cord to the harness, use a locking krab, clove hitch the cord midpoint into it.

Jk

To add a second attachment point, you can tie exactly what you have in your photo, but allow enough rope to tie a small alpine butterfly in the centre of the rope - and then clip into that. Also you can use a barrel knot to attach the carabiner, so that it's held in place and is easier to clip.

I tried one last summer in the Alps and found it really useful for multipitch sport routes. Figure of 8 knots seem to be the way the French tie them. This video has a really good analysis, and the strength testing is pretty sobering. If ENSA recommend something, it's good enough for me!...

Thanks for posting.

just look up caving cows tails.

And you want barrel knots on the ends

Decathlon have them for about £8....
