Promaster 攝影棚夾具（附黃銅螺柱）

Finally, a clamp that doesn't slip under heavy lights—the brass stud feels solid and the grip is reassuringly tight.

Had a tough time with cheaper clamps before, but this one grips the light stand securely without any slipping. The brass stud adds a nice bit of weight and feels durable enough for daily studio use. Really happy with how solid this is.

The brass stud on this clamp feels really solid and doesn't show any wear after a few weeks of heavy use in my small studio. It grips firmly without slipping, which is exactly what I needed for positioning my lights.
