CR- OK, allow me to explain this art hanging system! it is comprised of rails and these clear nylon hangers. 6 pieces, each are approximately 79 inches long. This track clips onto the plastic mounting blocks, as shown with the screw that was used. Then, if all is straight and level, you clip on the rail hanging strip! Then, each clear vinyl string has a track end and an adjustable end. This is what you attach to the art/picture. Get it? This is a very sleek, unobtrusive device to showcase the art and not make a whole lotta holes in your wall while doing so! You get 6 rails, blocks/screws, cord hangers. The candle holder / pens are a bonus!
