A self-rescue system unit that features:

  • The FCX Descent Device that uses a unique cam feature that allows smooth modulation so the user can easily control the speed of descent.
    • Simply pull the lever to find the sweet spot to begin descent. If the user releases the lever and stops pulling, the descent device will brake instantly (See video tab).
    • If the user pulls the lever to its full extension, the descent device will brake as well (See video tab).
  • The TVAC descent line is compact measuring only 7.5mm (The 301SRK system rope measures 6.8mm in diameter) and stands up to heat on long descents.
  • System packed in a weather-resistant bag that will stand up to an electric arc flash.
  • Two retro rappelling straps to be used with an ‘H’ Style Harness without rappelling loops or an X-Style Harness without a sternal attachment loop.
