Manufactured by RAM Mounts, the 1.5-inch diameter ball and 2.5" diameter plate can mate to any professional camera head or any gear having a 3/8"-16 threaded stud.
Note: The 3/8"-16 stud on this part is larger than a standard camera screw (1/4"-20). This larger stud is suitable for mating with a tripod head or gear having a 3/8"-16 threaded hole.
