SmallRig 超級夾具 附1/4"及3/8"螺紋 (2入/包) 2058

I was a bit skeptical about the plastic thumb wheel, but it’s actually very sturdy and the 1/4" threads held my monitor arm perfectly.

Finally, a clamp that actually grips round rails without slipping off. I mounted a small LED panel onto a light stand arm, and the built-in thread adapters made setup effortless.

The dual 1/4" and 3/8" threads on each clamp mean I can swap a monitor arm or a mic holder without hunting for adapters. They grip my light stand's tube firmly, no wobble, even when I tightened them one-handed. Two in the pack, so I've got one on each side of the rig.
