The formfitting full cage frame features a slide-in ARCA-compatible quick release attachment for camera to easily fit in and out from the base plate, a built-in cold shoe mount at the top and an ARRI Rosette mount at side. You're free to install handle grips onto the top or one side of this cage frame, or install an NATO clamp for external accessories, or install a rod system underneath the base plate for rod-mounted accessories like matte box or follow focus.
