Make aid climb through overhanging sections a little easier with Petzl's Evolv Adjust keeping you closer or farther from the wall. This positioning device uses two adjustable arms that connect to your aid equipment, pull you closer to the higher piece, lower you to the bottom piece, or adjust for the ideal length. Each connector has a retainer that specifically fits Petzl's Spirit Screw-Lock carabiner, and these retainers keep the rope out of the way for easier clipping. This device is designed for use below the anchor points and should only be used when the potential fall factor is less than one
