Descenders

Descenders are specialized tools used in climbing for controlled rappelling down a rope. They act as friction devices that convert the rope’s potential energy into controlled descent by adding friction as the rope feeds through the device.

• Function: Descenders allow climbers to safely rappel down a rope at a controlled speed, enabling descent from cliffs, lowering injured climbers, or maneuvering during multi-pitch climbs.
• Types: There are various descender designs, each with its own advantages and applications. Some common types include:
  • Tube-style descenders: Simple and robust, offering good friction control. (e.g., ATC Guide)
  • Rack-style descenders: Efficient for rappelling, often used in professional applications.
  • Assisted-locking descenders: Provide additional safety features like auto-lock mechanisms for extra security.
• Safety Considerations: Using a descender requires proper training and knowledge of rappelling techniques. It’s crucial to understand how to operate the specific descender model and practice safe rappelling procedures.
