The Delta 1 Muslin Mover Single Wall 16' System comes in several different sizes. It is a ceiling mounted system. Ever visit someone in the hospital? Have you seen those ceiling curtains that get drawn every time they do something private to a patient? That's the system.
The Muslin Mover attaches to regular, or drop ceilings, or to walls, with optional L Brackets. Backgrounds are attached to smooth traveling carriers that are dual-wheeled, and made of nylon. It compresses 10 ft backgrounds to as little as 18 inches, depending on the thickness of the material you decide to use.
It does not come with muslin, or any other background. You provide that. What it DOES come with: straight and curved track sections, one carrier, and one clip for every foot of track ordered.
The Muslin Mover comes in Single, Two, Three Wall Systems, complete with curved and straight track sections. They are also available in a complete Oval System.
