Designed to give the climber a super-strong anchor connection while threading for the lower, setting up a rappel or belaying. The PAS should replace the daisy chain affixed to your harness for belay change-overs, primarily because daisy chains are strong only when loaded in the end loops (intermediate pockets are only 300 lbf/1.3kN). Additionally, the PAS doubles as a handy anchor equalizer or runner when removed from your harness.
