Different Rosettes Sizes, please help explain

[steve green]

Can someone please explain the different Rosette sizes. GDU sells "Arri Standard". Seems as though Tilta, Mark Peterson, for his Horseshoe Top Plate, and Wooden Camera all sell "Arri Rosettes" but they have a smaller thread size. The teeth are the same but the thread size is different.

I found this valuable, Steve. http://wiki.apertus.org/index.php/Rosettes

I can confirm that the following parts are ARRI Rosette 60 Tooth Rosette with M6 internal thread.

Cameron,

Super helpful, thank you! That's what all of my rosettes are, so called Arri Rosette M-6 thread. That makes sense. What I don't understand is the GDU version of the Arri Rosette.

Different thread, it's larger then M-6, so strange. I bought these to use on my Komodo with their Timmy Ribs and none of my Arri Rosette Handles would work.
