Show Description

A single rope autoblocking device that excels for single pitches (can't rappel on double ropes with it). The 2.0 version gets added effectiveness for belaying, catching and supporting someone who likes to hangdog.

  • Solid braking for snappy catches and easy holding (for a leader who likes to hang and work projects).
  • Belay tube-like geometry quickly feeds rope.
  • Recommended for use with 8.7 to 10.5mm diameter ropes.
