3162 is designed to attach to camcorders or camera cages with 1/4”-20 screw and 3/8”-16 screw to prevent twists and fit in the RS 2 and RSC 2 gimbals. Compared with the original Arca plate, the plate is extended 25mm longer and increases the range for left and right adjustments to mount cameras in special shapes, such as BMPCC 4K camera equipped with a cage. A built-in magnetic flat head screwdriver is placed on the bottom for easy assembly and disassembly. Rubber pads are featured on the top to protect the camera and cage from scratching and increase the friction to secure the connection.
