Ballhead Magic Arm Features

The ballhead magic arm consists of two ball heads and a ballhead clamp. It includes an anti-twist design that secures the arm to the crab-shaped clamp to prevent disconnection. The bottom ballhead has a hex hole for enhanced fastening using an Allen wrench.

The 360-degree adjustable ball heads feature anti-slip threads for easier locking. Each ball head includes one 1/4"-20 screw for quick connection of action cameras, monitors, LED lights, microphones, and other accessories.
