The Kupo KCP-101W Max Arm with wheel handle is an adjustable wheel arm that has two studs connected to ball joints at the ends, and a central elbow that can be rotated 360 degrees to allow you to position your camera, accessory, or lighting fixture quickly and easily. With the spigot and elbow joints loosening or tighten simultaneously with a single handwheel, the max arm is a versatile gripping tool that allows quick easy positioning. The Kupo Max Arm is equipped with replaceable friction discs with anti-slip rosettes that prevents unnecessary movement. The larger rubberized hand wheel then slowly increases tension until all joints lock at once making precise positioning with ease.
