Another interesting biner

And, again, a dead-end trying to find more info...are there bloodhounds with better noses?

What sort of additional info are you looking for? It's a specialty biner for top-rope anchors. Kinda lame that you can't use it outside, but it seems like dirt and rock would trash it with the quickness.
Personally I'd rather have normal screw gate and a sheave.
