It's very rare for an image maker with a studio (even a small one) not to have a backdrop support system for hanging seam paper, muslin, or canvas backgrounds, and you can take some of them like this Neewer Backdrop Support System on location.

The kit includes four crossbar sections that can be joined to measure 5 to 10' for nearly all seamless paper rolls, as well as muslin and canvas backgrounds weighing up to 8.8 lb. Maximum height is 7', minimum height is 27.5', and the folded height is 29.5'. Three clamps that open 1.4' are included to hang the muslin or secure the paper, as are two sandbags that ship empty so that you can fill them with the weighty material of your choice. A carry case is included to take the system on location.
