Can this type of clamp be replaced? It is fixed to the base portion of a light stand and the handle (yellow) tightens on the extension which slides out of the base vertical for raising or lowering the light. I don't want to replace the light stand, if possible. I have tried Googling clamp for light stand resulting in hits that have nothing to do with what I want. Does this part have a dedicated photography name that would narrow down my search results?
