Product Details

The ISC Singing Tree Rope Wrench


The Singing Tree Rope Wrench is a revolutionary SRT (Single Rope Technique) climbing tool. Designed by Kevin Bingham from Detroit in the USA.

The ZK2 is the latest version, manufactured by ISC. The Rope Wrench comes with a mid-line pin to allow quick installation on your climbing rope.


  • The ZK2 is made of aluminum and is lighter and smaller with a much slimmer profile than the original ZK1 version
  • Rounded machined edges and curves make it rope friendly and climber friendly
  • The mid-line "Slic" pin is now included
  • Easy to open with an allen key for tether installation
  • The bottom friction pin features a roller sheave for a smoother ascent and descent. The upper friction pin includes a larger diameter "slic" pin. This provides more consistent friction and is more rope friendly
  • The stiff tether (sold separately) forces the Rope Wrench to quickly engage or disengage
  • Can also be used with a soft tether made from accessory cord or webbing (not included)
