The ARRI Rear Accessory Bracket RAB-1 is designed to mount accessories like battery plates or power-splitting boxes to the ALEXA Mini camera body. This curved bracket screws onto the camera providing a rib-like structure on which to attach a power solution. Use the RAB-1 bracket with the separately available RAB-1 Clamp to attach an ARRI Power Splitting Box, or a BAP-1 Battery Adapter Plate.
