Use this ARRI Standard 12″ Dovetail Plate from SHAPE when balancing front- or back-heavy camera loads. The studio bridgeplates 19 mm or 15 mm Arri standard (DPK19, DPK15) can easily slide onto the lightweight ARRI standard 12″ dovetail plate for additional leverage and mounting options. Both the aluminum, Teflon-coated design and tapered ARRI dovetail configuration allow your mounted equipment to slide back and forth easily. A stopper screw on one end and a safety latch on the other prevent your equipment from accidentally sliding off the plate. There are twelve 1/4″-20 and five 3/8″-16 threads down the center of the plate for mounting.
