Placed in the vertical plane TRADITIONAL RAP ANCHORS load each bolt simultaneously which eliminates any worry about potential shock loading in the event of rock failure. This is the cheapest, lightest and preferred stainless steel "chain" anchor system suitable for sport, trad, mixed and big wall routes. Be sure to clip into each hanger - not the chain itself for anchoring and belay purposes. Affix with stainless steel WEDGE BOLTS - single or double expansion for more holding power in softer rock. All stainless steel construction.
