Finally --a convenient way to store muslin backgrounds in very little space while keeping them ready for instant use. Muslin backgrounds attach to the Muslin Mover with spring clips, which attach to dual wheeled nylon carriers. The carriers glide effortlessly along tracks in the rail, so backgrounds can be stored on either end of the rail, then rolled into camera view when needed. A 10 ft. wide background stores in only about 18" of space when mounted on the Muslin Mover, to make best use of prime camera room space. Using 8-10 clips and carriers for each 10 ft. wide background is recommended. The locking muslin spring clips do not damage backgrounds. The Muslin Mover Rail System mounts to walls or ceiling with common hardware store screws, anchors, L brackets, suspended ceiling clips, etc., and complete instructions are included. It holds muslin backgrounds in a minimal amount of space, and speeds changing of backgrounds. Easy to install rail system mounts on wall or ceiling and features modular design so pieces can be added to match your size requirements. 450520 includes 6 track carriers and 6 muslin spring clips.
