Petzl Connect Adjust
A lanyard with a speedy-length-adjust mechanism. It can adjust smoothly from 15cm to 95cm.
This is a great advantage in aid climbing off bolts where height gain with each upwards movement is maximised, as there is little loss.
Best used with smaller screwgate karabiners such as the CT Nimble. Note that the Connect Adjust is a positioning device and not an energy absorber, and therefore should not be a link in the safety chain if greater than Factor 1 falls are anticipated.
