Manfrotto 175 Spring Clamp

The clamp range from 5 to 40 mm is perfect—it grabbed my light stand's thinner leg just as securely as the thicker one. I’ve already used it to mount a small rig on a 38mm bar, and it held rock-solid without any wobble.

I needed a clamp that could handle my thicker light stands, and this one grips bars up to 40mm perfectly. The Type 17 attachment locked onto my equipment without any wobble.

Finally got tired of my backdrop slipping and this clamp solved it—the 40mm max tube diameter fits my light stands perfectly and the double attachment system means I can mount accessories on either side without any wobble.
