RPs come to you from down under, where they were first developed by Roland Pauligk to protect the thin, shallow cracks of Mt. Arapiles. Their more symmetrical design and softer metal offer more contact and secure seating in small placements. Soldering allows for thicker wires to be used on smaller heads. The smaller sizes are rated well below the forces that may be developed in even soft falls, and the smallest size is only for direct aid.

  • Stainless steel wire silver soldered into brass
  • Brass heads bite into the rock
  • Colour-coded plastic wire sheaths and loop covers make for easy identification (and prevent catching in carabiner gates)
  • Tested under static hydraulic load
