Kupo Grip Arm Support This is especially designed for giving the most support to a grip arm. It is constructed with an extendable aluminum column, and comes with the ball joint pivot clamp in one end, and an angle-adjustable attachment on the other end. The attachments can also be easily fitted into the 3 and 4 Way Clamp System for quickly coupling the stand tube from 35mm to 50mm with its spring locking design. With this functional support arm, the loading weight of a grip arm could be increased and a sliding problem could be solved. The Grip Arm Support has a built in ball joint that rotates 360 degrees for infinite flexibility and extends from 22 - 30.7" (56 - 78cm). With the addition of the Grip Arm Support the load capacity at the end of your grip arm is greatly increased.
