The Top-Mounted Cheese Plate for Blackmagic URSA Mini/Mini Pro/12k from Wooden Camera attaches to the camera top by the included 1/4"-20 screws. It is festooned with 1/4"-20 holes with standard 9mm spacing and multiple 3/8"-16 holes for mounting large accessories without stressing your camera's body. Multiple ARRI accessory mounts (3/8"-16 threaded hole with locating divots) are also machined into the top and side of the plate. The plate includes a tape hook for accurate focus measuring. The original Blackmagic handle can be reinstalled on the Top Plate, using the center 1/4" holes.
