Would people build an anchor used for bottom roping and therefore lowering a climber with Wild Country's 10mm dyneema cordelette and a single large krab, ie

...assuming it is going to be equalised at 3 anchor points.

I'm sure it's more than up to the job, but just looks thin and no where near as confidence inspiring as rope.

Same on mine, but it is this cordellete: http://www.needlesports.com/acatalog/Mail_Order_Slings___Extenders_21.html which he is talking about. Its just above the "Tape on the reel" section of this page.

In answer to your original question - Yes, I would trust this. 10mm dyneema is pretty damn strong, and there are effectively 3 independant loops of it there, once you have tied in the knot. Yes, that connected to 3 anchor points using screwgates, and a screwgate to run the second rope through - I'd use it with no worries.

As an afterthought.... Quickdraw extenders are often made form 10mm dyneema, and I bet people take bigger falls on them than you ever will when toproping, yet we trust them.

In reply to Enigma: Thanks, common sense says that set up is fine, but still good to hear it from others.

I suppose that once the overhand knot is tied, its just the same as having 3 seperate, smaller slings. Would you set up a top rope on those?

Even one strand of dyneema is strong enough PROVIDED it is protected from rubbing edges.
