Looks like a self belay device for sport climbers that rock exoticia put out about 15+ years ago what a P.O.S. that was!!! As Jeff just stated 100kg=220lbs and if that is the working load, it ain't sh*t, saw no OSHA approval either. I love checking out and trying new gear but until I read/see more on this product it seems sketchy to me.

Take it easy now guys this really is not a load bearing part of the system. It's just to help ease in tending the line on return. The Back-up and hitch both would be loaded if you slip.
certifications:
EN 353-2
EN 358
EN 567
EN 795B
EN 12841 A/B
seems to carry everyone there is.
If yea read it says "BACKUP
supports also the strongest stress (fall
factor=2) in semi-dynamic way, and it
avoids the shocking effects on the ropes
caused by the traditional self-locking
devices with toothed cams."
What I get out of this is it is desinged to actually slip on the rope a bit before it locks off. So all you 220+ Lb tubbies wont break/cut the rope.
