The SHAPE Arri rosette 15 mm studio rod bracket is designed to mount handgrips or other accessories on each side. It fits on 15 mm sudio rods and features ARRI rosettes on both ends. The ratchet knob and cuff system allow you to easily clip or unclip the block to your rig without removing accessories in front or behind (matte box, follow focus, lens support, zoom motors). The SHAPE cuff system allows you to install your handles or other accessories in one clamp quickly. By pressing the block below the rods and locking the cuff with a ratchet knob, the cuff system is super strong, providing you with the most solid system on the market.
