The Petzl Ascension Ascenders are the benchmark for handled ascenders and have been refined to provide greater comfort efficiency, ease of use. The ergonomically shaped grip is over molded with rubber for greater friction and the broader surface provides greater comfort while pulling on the ascender. The grip is wider at the bottom providing better comfort for your hand during use. The index finger indent has also been increased offering greater efficiency when pulling on the ascender. The trigger to openclose the cam is now recessed inside the frame to avoid accidentally opening the cam while in use. The cam has been redesigned to minimize friction when sliding the ascender along the rope while the angled teeth provide secure grip in the worst conditions wet, icy, or on muddy ropes. The geometry of the single piece aluminum frame ensures optimal handle orientation when the device is loaded and will maintain solid, comfortable performance even after thousands of meters of jugging.
