Genius Double-hook für everything

Often i have to install diffusors or backgrounds for photography.
My problem was to hang this stuff with transverse spars. C-Clips are not smart because you have different ones for every diameter.
A simple solution here: print two of them, connect them with a rope and add things you need (in my case i attached clinches)
The mounting point of both parts is exactly under the middle of the hooks, so the hooks are closed automatically.
This hooks are designed for every spar up to diameter 25mm.

Have fun with photography, Jochen Nunz Herz
