This backdrop kit includes a 20ft straight backdrop, a portable aluminum frame, 2 shelving racks, and a pillowcase fabric graphic. The shelving racks can be placed in a variety of positions along with the frame, as the top clips snap in place to fit the sloped edge as you adjust. Each rack consists of 3 shelves and a bracket that holds a 42 inches (or within 42inches) monitor for digital signage and promotion purposes. The shelves are sturdy enough that you can show a variety of products, giveaways, and literature without fear of tipping or breaking.
