When you need to go extra tall or wide with your backdrop or seamless paper setup, this is the kit you'll need to make sure everything is well supported and stays where it should. The expandable crossbar can accommodate backgrounds up to 12.9 feet wide, and the stands will raise that crossbar up to 13.5 feet in the air. Total capacity is 38lbs, so you can put a large roll of seamless paper on it without fear.
