The 500 Series is a heavy-duty track that can be used for straight or curved applications in TV studios, theatres,
and many other types of facilities. Curves are typically formed at the factory to suit your project requirements.
Walk-along tracks can be curved to virtually any shape or length. Cord operated tracks can be rigged with
serpentine or reverse curves. The 500 Series is most often motorized, or manually cord operated for short
runs and light weight curtains.
The ease of operation of a 500 Series track is dependent on several factors, including the radii of the curves
and whether reverse bends are part of the track layout. In general, the tracks operates best around gentle
curves. Whenever possible, it is recommended that layouts be designed with radii of 4 feet, or larger. Tighter
curves will result in a system that requires additional effort to operate.
