Use the ProMaster Heavy Duty Background Support Bar with two standard light stands to create a complete system for backdrops or roll paper up to 12' wide! This 4-section crossbar snaps together easily and each end mounts to a light stand's 5/8” stud with ¼”-20 screw mount. It can be configured in three ways to best match the size of your background. Use two crossbar sections to accommodate 5'-wide backgrounds; three sections fit backgrounds up to 9'; and connecting all four sections accommodates backgrounds up to 12'. The longest crossbar sections measure under 42”, making transportation and storage easy.
