The Harken Ninja MultiAscend is a versatile rope access and rescue ascender designed to improve efficiency during ascent, progress capture, and work positioning operations. Featuring an innovative dual-cam design, the MultiAscend functions as both a chest ascender and a primary attachment point, making it an excellent solution for rope access technicians, rescue professionals, and industrial work-at-height applications.
