400 Series Heavy Duty Straight Track

  • The 400 Series is a straight track in many models for various project requirements. This heavy-duty track is available in galvanized steel, black powder-coated steel, and mill-finish aluminum. In addition to the traditional zinc-plated finish, all hardware items are available in black to meet the demands of the theatrical industry.
  • Model 401S is recommended for moderately heavy curtains up to 60 feet wide. It utilizes ball bearing carriers with polyethylene wheels and 4″ end pulleys. Model 428S is an economical upgrade to urethane wheels and 6″ pulleys when a quiet track is desired for larger curtains.
  • Models 416S and 418S feature improved carriers with a custom-designed, sealed ball bearing in each wheel. The 416 carrier has nylon-tired wheels to minimize friction when moving heavy loads. The 418 carrier has been redesigned with a urethane tire that combines durability with quiet operation. Each is complemented by 6″ end pulleys for rigging curtains of virtually any length. The Premier versions, Models 416P and 418P are the best in heavy-duty straight tracks. They incorporate 1/2″ operating line, rear fold guides, and 8″ end pulleys for maximum ease of operation of very heavy stage curtains.
