Configured to facilitate ascent using a double rope technique, the Petzl ASCENTREE takes a familiar form and spins it to the needs of arborists. The two ergonomic, molded handles allow access even when using large gauge gloves. The self-cleaning, toothed cams promote excellent traction, even on frozen or muddy ropes. Multiple lower connection points allow for varied ascent and positioning techniques, while two upper connection points make capturing the rope with a carabiner simple. Doing so will prevent any accidental removal from the rope channel.
