 "Kupo 40-Inch Extension Grip Arm with Big Handle - Silver, KG203412" "Camera & Photo Accessories Page 3201 | All Tech Toys"
"The 40 Grip Arm with Big Handle, KG203412 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 gobo go between the light and a subject such as flags, scrims and silks as well as other accessories virtually anywhere."
