The Linkstar ES-1 Paper Roll Holder is a spare set of paper or vinyl background roll holders for the ES-3. Additionally, it is possible to use the Linkstar paper roll holder as a hanging system for a cloth or paper background roll in combination with the Linkstar BSH-3. Two roll holders are supplied. On the roll holder without chain you will find a rotary knob that allows you to adjust how light or heavy the paper rolls off. The last picture shows the dial.
