Petzl® I’D® S Control Descent Device

Self-Braking Descender for Work at Height & Rope Access

Designed for work at height and rope access applications, this self-braking descender delivers smooth, controlled descents with built-in safety features that help reduce user error.

Easy to Use

• Safety gate on the moving side plate allows the rope to be installed while the device remains connected to the harness
  
• Clear markings and an integrated rope guide simplify rope installation
  
• Anti-error catch helps reduce the risk of incorrect device installation
  
• Ergonomic handle provides precise rope release and comfortable descent control
  
• Two descent modes: via the side plate or the V-shaped friction channel
  
• Anti-panic function automatically stops descent if the handle is pulled too aggressively
  
• Allows smooth movement on inclined or horizontal terrain
  
• AUTO-LOCK system enables easy work positioning without tying off or manipulating the handle
  Rope locks automatically when the handle is released
  Automatic handle return reduces the risk of accidental snagging
  
• Handle automatically returns to the storage position when the rope is removed, minimizing snag hazards while carried on the harness
  

Versatile Performance

• Once locked, rope can be taken up without using the handle for reversible haul systems or short ascents
  
• Cam can be manually operated to feed slack or belay a lead climber using climbing techniques
  
• Moving side plate locks with a screw, allowing secure integration into rescue kits
  
• Optional auxiliary brake (open or closed) can be added to improve descent control based on user weight and rope diameter
