The black SHAPE Compact Quick Handle ARRI Rosette consists of a left- and right-hand articulating arm with rubber handgrip. Each arm features a rosette with an M6 metric screw for attaching the handle to cameras and baseplates with ARRI rosettes. Each handle features two points of articulation actuated with SHAPE's patented quick-lock buttons.
The arms attach via the rosettes allowing you to select the attachment angle. Each arm also has two each 1/4"-20 and 3/8"-16 threaded mounting holes with anti-twist indents for attaching accessories. The quick-lock buttons are located at the articulation points, one towards your baseplate and the other controlling the angle of the rubber handgrip.
