The Leofoto AM Series "Heavy-Duty" Versa Magic Arm Kit is a multi-purpose tripod accessory that attaches to the leg of select Leofoto tripods, or other tripods and camera brackets with a 3/8th mounting hole. The magic arm allows a light, microphone, monitor, smartphone, tablet, or even an additional camera to be affixed to a camera rig without the added bulk of a clamp. Each end of the magic arm features a ball-and-socket joint that rotates 360°, and the center elbow joint locks in any position. The large, easy-to-grip center knob locks all three movements simultaneously for quick and easy setup and repositioning. The "kit" version features anti-twist lock adapters on either end as well as 1/4" and 3/8" mounting adapters.
