Fitting Types

  • Non-Tensioning

    Non-tensioning fittings are coupled with tensioning fittings to support the cable as it is tightened to the appropriate level to pass building code requirements.
  • Tensioning

    Every cable run needs at least one tensioning fitting to ensure the cable can be made taut enough to pass building code requirements.
