The Ninja MultiAscend is engineered to provide increased efficiency in a range of applications. The dual cam design enables the MultiAscend to act as both a chest ascender as well as a full point of attachment. The innovative dual-stage locking swingplate ensures consistent engagement with the rope, preventing unwanted detachments. In addition, the external release triggers make adjusting the Ninja MultiAscend safe and easy when used as an ascender or a progress capture device on a safety line.

  • The MultiAscend started life as a mild-mannered chest ascender leading a double life as a full point of attachment. The details about its locking safety release (on the opposite page) show how it lives up to that—and how climbing with its double-cam design, saves energy all day long.
  • Handling the sleek-machined aluminum chassis with the external release triggers got us thinking: the steel double-cams reduce the effort needed to slide this up the rope so much, the MultiAscend could do double (or triple) duty as a hand ascender or a progress capture device on a safety line.
  • There are two release triggers designed to make downclimbing easier too. Two fingers are all it takes to disengage the two cams.They stay outside—no sticking them inside where they can get caught. All the while the unit stays fully enclosed around the line. MultiAscend = safe and efficient.
