A Hex Grip Arm (or Gobo Arm or Boom Arm) for a C-Stand can be used in conjunction with a 2-1/2” grip head (KG203012), giving you complete flexibility to position a gobo such as flags, scrims and silks as well as other accessories virtually anywhere. The surface of the tubing is painstakingly machined to create a rough texture to ensure a non-slip surface. The 2-1/2” grip head consists of a pair of rotating aluminum discs attached to a 5/8” (16mm) receiver. The discs have four different sized "V" shaped jaws to accept any accessory with a 5/8”, 1/2”, 3/8” or 1/4” mounting stud or tubing. Also features an oversized ergonomic "T" handle and dedicated roller bearings designed for maximum torque, and constructed around a solid steel central bolt with a fixed solid pin to secure it to the aluminum casting for increased strength and durability.
