Functionality & Usability

The SOB Figure 8 Climbing Descender is exceptionally easy to use, even for beginners. The figure eight design allows you to adjust friction by simply tightening or loosening the rope around the device. This provides a smooth and controlled descent without requiring complex maneuvers or adjustments. To initiate your descent:

  1. Pass one end of your rope through the central hole of the descender.
  2. Feed another length of rope through each arm of the figure eight, creating a loop on either side.
  3. Clip the carabiner to the belay sling or harness attachment point.
  4. Gently pull down on the working end of the rope to begin your descent. To control your speed:
  • Tighten the rope around the device by pulling on both loops simultaneously, which increases friction and slows you down.
  • Loosen the rope around the device by pushing outward on each loop, decreasing friction and allowing for a faster descent. The figure eight shape ensures that even if the carabiner accidentally unclips from your harness or belay sling, the descender will not slip off the rope due to its designan important safety feature during critical situations.
