Help identifying a wing rigger

I don't remember any identification labels on the rigger, I'll double check that. The issue is not the leading edge shape. The rigger is so wide I can't clamp the wing safely enough. And when I rotate wing it doesn't stay rotated under its own weight, meaning the pivot point should be closer to the leading edge. And also I used another Cobra rigger which was a bit smaller than this and fitted wing better.
