Q: 4. I already have the Kupo C-stand with Turtle Base, the steel baby boom arm and the grip head. However, I like the idea of the Kupo Pivoting Boom Arm Clamp. I am having trouble, from the singular image, how it will actually works with the boom arm. It might seem like a silly question, but how does the pole fit into it? Or, is this accessory for another type of boom arm? Thanks for your time!!

A: The riser from a C stand is inserted in the tube that you see in the top of the image of this product. Then you twist the handle on top to tighten it in place. So, this product basically allows you to use a C stand riser as a super-sturdy boom arm.
