Introducing the latest addition to the patented Infinity Arm - the Matthews 429626-12 Arri-style Anti-Rotation Tip with 3/8" thread. This simple solution allows for safely rigging the Infinity Arm onto popular cages and camera accessories featuring anti-rotation 3/8" receivers, eliminating lefty-loosey concerns. Locating pins provide support and security for the 3/8"-16 thread mount, securing mounted equipment and accessories in place during jarring, whipping, and jostling moves.
