Anthron Descender

The Anthron Descent Controller is a manually operated controlled descent device. It is most commonly used for suspended work positioning, self evacuation, or rescue operations. The device utilizes a cam assembly that provides friction on the rope to hold a load, or allow the load to descend at a controlled rate. To begin descent, the user depresses the control lever on the Anthron. If the control lever is fully depressed in a panic situation, the descent will stop. In most applications, the Anthron operator attaches the rope end to an approved anchor and descends suspended from the device in an approved harness, or bosun’s chair. The Anthron can also be inverted so that the device is attached to an approved anchor, and the rope end is attached to an injured person. In this orientation, the injured person can be lowered while being controlled by a rescuer. Other features include:

  • Proper roping/rigging diagrams on the side of the Anthron Descender
  • Device can be installed/removed at any point on the rope
  • Working load of 300 lbs (136 kg)
  • System consists of a 7/16” (11mm) rope, the Anthron Descender, and 2 carabiners
