The Tilta Professional Side Arm Handgrips allows you to handle your shoulder-mount system comfortably and securely. Each handgrip comes connected to an adjustable extender arm with which it interfaces via a standard ARRI rosette. A second ARRI rosette on the other end of the extender arm enables a secure connection to your rig. The arms extend from 6 to 8.1" in length using built-in thumbscrews, allowing you to quickly and easily adjust the handgrips on your shoulder support system.
