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.
