These are a project designed to make anchors that are over 20kn very quickly and easily. The origial insparation was for rope rescue, but it can be relevant for many other disciplines. It is made from 6mm dyneema rope with a minimum breaking strength of 36kn.  The advantage of this eye-to-eye configuration is that they eyes on the end are double strength, so it can be very strong when hitched onto hardwear, or when chokered around a tree or boulder, and you can hitch multiples together to make a longer device. 
 
With this sort of 12-strand dyneema rope, when we use it to equalize anchors by tying a master point, all of the testing I have done and seen supports the idea that you get 1/3rd resigual strength. So for this cord when you attach it to two points and tie a loop you have 1/3 of 72kn (two strands of 36kn.) That means a master point of about 24kn.  All of this for very little weight, a 10-footer weighs about 110 grams.
 
Eye-to-eye slings have endless uses. You can choker it around a tree or rock and have a 27kn anchor very quickly. Choker or fold it in half and girth hitch it around a tree to make a high directional. I take them alpine climbing and use it to sling large blocks and horns very quickly and easily. A friend who is a canyoneer figured out how to make retrievable anchors with them. In my fiddling around I found that the 6-footer was great for building a guide's 5:1. I also found it a decent length for jumping around a rescue system to pass a knot. 
 
When ordering, choose the overall length you want within the size range, and the size of loops you want at the ends. Many colors available so you can organize your kit.
