This Mitchell Mount Cheese Plate from Kupo is CNC-machined from a single piece of aluminum for strength, accuracy, and uniformity. This 10 x 10 x .5" plate features four countersunk mounting holes that allow you to mount it onto a variety of platforms, which then allows you to mount a Mitchell mount head on that platform. The plate features four slots that act as keyways for your head's key, preventing the head from twisting once mounted. Forty-eight 3/8"-16 threaded holes spaced 1" apart allow you to mount a variety of accessories.
