Pick up this Manfrotto Green Chroma Key FX Portable Background Cover to expand your keying options. This is just the cover—it is intended to work with the Chroma Key FX Portable Background Kit's aluminum frame and clips, which is available separately. The kits come in either blue or green, so this cover can be used as a second color choice to add to the kit color you have, or simply as a spare. Like the background that comes in the kit, this cover boasts a large 12.7 x 9.1' size to produce a workable surface area of 120.5 square feet and simply clips into place on the frame.
