The Super Clamps with Dual Ball Head Magic Arm from Ulanzi features two clamps that can attach to flat or round surfaces while holding a camera, smartphone, LED light, or other accessories up to 7.7 lb. The durable aluminum clamps are joined by a center magic arm with two ball heads for 360° rotation, so you can position your accessory at almost any angle. There are 1/4"-20 screws on each end of the magic arm that can be used without the clamps as an option.
The jaw openings of the clamps extend from 0.5 to 2.3" and can be adjusted by their locking levers. Nonslip rubber pads are built into the clamps to prevent scratching and slipping, and they feature 1/4"-20 threads for additional mounting options. A ball adapter with a 1/4"-20 anti-twist, nonslip thumbscrew is included to swap in on one of the ends to accommodate a monitor, light, or accessory with a 1/4"-20 thread.
