Meant for use with a 2.5" grip head, the steel-constructed Super Grip Arm with Swivel Grip Finger from Kupo adds greater flexibility and articulation to the standard grip arm that's often used with C-stands. Especially valuable if you're shooting overhead or need an extended range of movement from your light source, the arm has a 5/8" Super Grip Finger with an etched, non-slip surface attached to a swiveling ball joint. The finger is locked down securely with a ratcheting handle that can be repositioned for maximum torque.
