The Manfrotto StudioLink Chroma Key Blue Connection Kit 3m joins the screens together side-by-side to create various configurations such as a 360-deg enclosure. The kit includes 3 hinge brackets that join the aluminium frames together as well as a clip-on chroma key joining strip. The strip conceals the aluminium frames and the hinge brackets. The joining strip also features a 6-inch sewn-in skirt on the bottom edge to conceal the aluminium frame supporting it. This allows for seamless blending of the cover and the strap with chroma key flooring or other panels.
