The Metolius Personal Anchor System PAS, is a must have for anyone who climbs multi-pitch routes, big walls, or guides for a living. The PAS is constructed with a super strong, proprietary Power Webbing that attaches to your harness and when you get to your belay station or anchor, you use it to clip in and secure yourself. Daisy chains should NOT be used because they are full-strength only when loaded in the end loops intermediate pockets are only 300 lbf/1.3 kN. With the PAS, you can clip into any part of the system and you will get full back up as each loop has 100 strength to any sort of pull, fall or tension. The PAS is more convenient and adjustable than using slings, or quickdraws at the anchor when rapelling, or belaying.
