A best seller from day one the Ropeman 1 and 2 have become the ubiquitous tools for a wide range of mountaineering and cragging activities. From prussiking to pulleys and mouflage the list of uses and adaptations for these small but perfectly formed devices goes on and on.
The stainless cam allows a more complex (and more aggressive looking) but ultimately more rope friendly design, which gives bite on thinner cords that the Ropeman 1 doesn't have. This meant for many of the Alpine activities that people were using the Ropeman 1, the Ropeman 2 was a much safer alternative and with the pair of them available customers had a choice.
Thus the bottom line and the most reliable piece of safety advice is to follow the simple rule that the Ropeman Mk1 is for single ropes only while the Ropeman Mk2 will cover both half ropes and single ropes. Please make sure if you are purchasing a Ropeman Mk1 or Mk2 that you fully read the instructions and make sure that the use suits the device you have bought. And please remember if you are ‘adapting’ it for other uses that may not be fully recommended you are fully aware of the risks inherent for you or your partner.
