Features and Benefits

  • New Joint Guard Protection System dynamically indicates proper joint tension through color for easy installation and maintenance.
  • Lighter Weight mean faster installation than with other busway and lower installed cost that cable and conduit.
  • Field-adjustable isolation joint allows for ±½" per joint providing flexibility on the job-site.
  • Plug-assist allows for faster, easier installation of plugs which provide power to downstream devices.  Watch Video
