Product Details

  • 2 safety features: the anti-panic function is triggered and stops the descent immediately when the user pulls the handle too abruptly; the descent is automatically stopped when the user lets go of the handle.
  • Thick metal in high friction areas helps to increase the device’s lifetime in high use environment.
  • The handle allows the rate of descent to be finely controlled and its 360 degree rotation facilitates its use. Its aluminium body is covered with a grip enhancing material. In addition, an audible clicking sound accompanies the handle’s rotation to help the user to identify the handle’s correct position.
  • The device is locked using a metal button which prevents it from accidentally opening whilst ascending a rope.
  • Movement along horizontal or low incline surfaces is made easy by simply controlling the cam with your thumb.
