The 12mm Single Unit Petzl Coeur Bolt Hanger available at OmniProGear resists corrosion in typical exterior environments. Made of 316L stainless steel, the hanger is thick and has rounded edges at the connection hole, the combination of which results in a lot less wear of the connectors. Carabiner clipping is facilitated by the amply sized ergonomic connection hole, which is wide enough to enable two carabiners to be installed simultaneously. The hanger will not turn during installation of the anchor or when it is heavily laterally loaded while in use because the anti-rotation system features a textured back. The Coeur Bolt Hanger, which is also available in 10mm, comes with a three-year warranty from the manufacturer.
