I have a clone of the SP clamp you linked to. Unless you know the diameter of what you are clamping to is less than an inch, I wouldn't recommend it. I have a heavy-duty light stand and that first clamp's opening will not go around it. Works fine on a friend's Bogen and on electrical conduit but not on my stand. I noticed SP didn't give specs on how large a pipe it wil fit while the Smith-Victor from B&H will fit pipes up to 1.75" diameter.
