Petzl COEUR mountaineering anchor fabricated from HCR 904 stainless-steel for High Corrosion Resistance. Designed to be used in ultra-corrosive environments, like sea side. The hanger features an anti-rotation system with a textured back, to keep the hanger from turning when being installed or when heavily laterally loaded. The wide, ergonomic connection hole facilitates more straightforward carabiner clipping and is big enough to permit for 2 carabiners concurrently.
