Designed to customize the mounts on your Tilta Mini Articulating Arm, this Ball Head with ARRI Rosette can add a ARRI rosette to your preexisting magic arm. The ball head attaches to the articulating arm's clamp. The ARRI rosette on the opposite end can mount on compatible devices and is tightened via the integrated knob. Aluminum alloy and stainless steel make up the ball head's design for a lightweight and durable construction.
