Features

  • This lightweight device attaches to the first quickdraw and increases rope friction, allowing a lighter belayer to catch and hold a heavier lead climber's weight
  • Thanks to the patented cam construction, only a fall or lowering motion activates the resistance, increasing rope friction
  • The rope is never blocked completely; instead, the device facilitates smooth handling and soft catches, allowing it to be used effectively for dynamic belaying
  • Assisted braking function increases safety during falls
  • Smooth lowering control provides confidence while lowering climbers
  • Intuitive handling makes it suitable for beginners and experienced belayers alike
  • Compatible with a wide range of single rope diameters (8.7–11 mm)
  • Boost Mode: Attach the Mammut Assist Belay Resistor to the first bolt using a locking carabiner, allowing for faster engagement with larger weight differences
  • Rated for mismatches of up to <77 lbs. when clipped to a quickdraw, or <99 lbs. in Boost mode with a locking carabiner
  • Durable metal construction ensures long-term reliability
  • Lightweight design minimizes harness bulk
  • Ideal for indoor climbing and sport routes
