With rosette and thumbscrew, it can be attached to ARRI Style Rosette, Crossbar, Rosette Arm, or existing ARRI equipment. Please note the diameter of the rosette is 28mm, uncompatible with RED rosette.
I use this handle in combination with the SMALLRIG Single 15mm Rail Clamp with Rosette 1555. The handle is very well made and lighter than I expected. I love that the rosette fitting enables me to adjust the handle at just the right angle.
