The 40″ Grip Arm with Big Handle is a 2 1/2″ grip head mounted on the end of a 40″ piece of steel tubing 5/8″ (16mm) in diameter. 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″ (16 mm) 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. The “V” shaped jaws have “teeth” that grab whatever is mounted between the plates securely. The 2-1/2″ grip head features an oversized ergonomic “T” handle and dedicated roller bearings designed for maximum torque. The grip head uses a non-slip aluminum friction disc that will maintain its durability over time that offers the user positive locking strength and precise control, and is constructed around a solid steel central bolt with a fixed solid pin to secure it to the aluminum casting for increased strength and durability. The 40″ grip arm is almost always used in conjunction with a 2 1/2″ grip head, giving you complete flexibility to position a gobo “go between the light and a subject” such as flags, scrims and silks as well as other accessories virtually anywhere. This stand is clad in a stealthy black powder coated finish.
