Use this perfectly symmetrical Kondor Blue 12" Arri Lightweight Dovetail Plate (Space Gray) when balancing front-heavy or back-heavy camera loads with a smooth back-and-forth slide. Safety release buttons on each side prevent your equipment from accidentally sliding off the plate. There are plenty of 1/4"-20 and 3/8"-16 threads down the center of the plate for versatile mounting.  This plate is designed to be identically functional from the front and back.
