Excellent hands free fall arrest.
When doing high rise rope work, i.e.. rappelling off of roofs etc to clean windows the Petzl ASAP is great. I use my working rope for me and a back up line with the ASAP and Absorb lanyard for fall arrest. once its on the rope it follows you down the line without manualy working it. It will go up or down depending on your needs, all hands free. Keeps those OSHA guys off my back.
