Climbing Technology RollNLock ascender/pulley



Ultra-light multi-function device for mountaineering, rope access work, rescue and self-rescue. Compact and easy to handle, it has three different modes of operation: ascender, pulley or progress-capture hauling pulley.

Main features:

  • the new design and the different colours of the side plates make using it even more intuitive;
  • it allows ascending the rope in accordance with EN 567 / EN 12841-B standards (ascender mode);
  • thanks to the ability of locking the cam, it can be used as a simple pulley for lifting or transferring a load in accordance with the EN 12278 standard (pulley mode);
  • it allows the direct lifting of a load, the creation of hauling systems and the rescue or self-rescue of a person, as in the case of a victim fallen into a crevasse (progress-capture hauling pulley mode);
  • when used in pulley mode, the rope is free to run in both directions; instead, when the hauling-pulley mode is used, the rope can only run in one direction and it is locked in the opposite one;
  • switching from one mode to another is intuitive and it can even be done with gloves on or while operating in difficult conditions;
  • its compact size and light weight make it an ideal companion to carry on the harness at all times, for any eventuality.
