Make the task of mounting your camera and other equipment an easy one with the Manfrotto 244 Micro Variable Friction Arm Kit. It consists of a nano clamp on one end and an anti-rotation attachment on the other. This arm kit is compatible with the 190 series, 055 series, and the 386B-1 nano clamp from Manfrotto. The anti-rotation adapter’s unconventional design ensures that the equipment is securely interlocked to prevent the arm from rotating. In addition, you can easily replace the attachments by using the hex key included.
