SILENT STEEL® is the most famous name in heavy-duty stage tracks. The model 280 steel series is used in the majority of stage installations with heavy weight curtains of any length, and is particularly quiet in operation. Models 281 and 282 are for use with especially heavy curtains. They are identical to Model 280 except neoprene-tired ball-bearing carriers are supplied with Model 281, while larger diameter floor and end pulleys and heavy duty nylon-tired ball-bearing carriers are furnished with Model 282.
Model 280 series tracks cannot be curved, and uses one carrier per foot.
