The black 3m Adjustable Background Crossbar from Ducame is a 3-section telescoping crossbar that adjusts from 1.25 to 3 meters. It is meant to hold a 3m or 9' roll of seamless paper or smaller cored roll, or any 3 meters muslin background. It fits on top of two stands with 5/8" studs. Two thumb screws secure the crossbar onto the 5/8" studs.
