This Petzl Coeur hanger is specifically designed for use in areas known for extensive corrosion. Using HCR 904 (high-corrosion resistance) stainless steel, this is one of Petzl's most durable units. But even with its heavy-duty construction, this hanger is still easy to use. Its wide, ergonomic connection hole allows installation of two carabiners at once. And its thickness and rounded edges along the connection hole help minimize wear and tear on the connectors. Like most of Petzl's hangers, it features a textured back that keeps the hanger from turning while installing the anchor or when it's heavily laterally loaded.
