After a long run-out, it's always a welcome sight -- a fat bolt and a Stainless Steel Bolt Hanger. S.S. Hangers are designed for use at belay stations, protection points (where no other option exists) and for rescue and rigging work. The clip-in point is large enough to accommodate two carabiners. Enviro Bolt Hangers are powder-coated to blend in with the rock as are the Rap Hangers. Designed specifically for belay and rappel stations, the Rap Hangers allow the rope to be threaded directly through the anchor for lowering or rappelling; they are unquestionably the best and lowest visual impact anchor out there.
