This extra-stable background system is particularly suitable for wide background rolls (2.75 m) but also works with smaller rolls (1.38 m). The tripod legs can be spread particularly wide. They are made from thicker tubes and are longer than the tripods of other background systems (2.90 m instead of 2.50 m). This system includes 2 tripods, 2 roll holders, and 2 clamps to secure the roll holders. A chain with a weight, which allows you to roll the paper in and out, is included in the delivery. The only additional item you need is a roll of paper in your chosen size. The tripods have extra pre-drilled holes so that two additional rolls can be attached. For this, you will need two additional sets of CBH-5 clamps and two B-Reel roll holder sets. Two roll holders are included. On the roll holder without the chain, you will find a knob that allows you to adjust how easily or heavily the paper rolls out. The last image shows the dial.
