This revolutionary device combines ascending and descending in one piece of gear. It easily threads onto the rope midline and can be used in both Doubled Rope Technique (DdRT) and Single Rope Technique (SRT), the Unicender fits the way you like to climb like no other tool. The Unicender utilizes unique friction plates that allow it to advance easily with minimal friction and virtually no “Sit Back,” giving you the most efficiency per stride. Descending is just as easy by looping the rope around the plates in SRT mode or Ddrt mode.
For rope size 11-13mm.
