Petzl Pirana - Descender


Petzl Pirana Descender


The PIRANA descender offers multiple braking options and can be installed on the rope without removing it from the harness.





  • Three braking positions
  • Two extra friction spurs allow friction to be varied during descent
  • Used with a carabiner with a cross-section of 12 mm (WILLIAM), it creates a rigid carabiner/descender unit that helps maintain noise discipline. The descender is used with rapid technique and is drop resistant.
  • Stays attached to the harness during rope insertion, to help prevent loss
  • Reduces the risk of leverage on the carabiner gate due to poor positioning
  • Helps prevent the formation of a lark’s head hitch around the body and reduces rope twisting, without decreasing braking friction


  • Weight: 90 g
  • Rope compatibility: for single ropes between 8 and 13 mm in diameter
