Often paired with a C-Stand, the black 20″ Hex Grip Arm from Kupo has a 5/8″ hex pin at one end of a 20″ textured, non-slip steel tube and a 2-1/2″ grip head at the other. The hex pin has 6 milled flat surfaces so that you can attach a light to it without it turning and use the arm like a mini boom. The grip head has a pair of rotating discs attached to a 5/8″ receiver. The discs have 4 V-shaped jaws to accept 5/8″, 1/2″, 3/8″ or 1/4″ accessories like flags, scrims or even another grip arm. The jaws are locked down by an oversized, ergonomic T-handle.
