The Petzl Coeur Anchor Bolt Hanger and Bolt Stainless Steel 10mm Single Unit available at OmniProGear is made for most normal exterior uses. The 316L stainless steel assembly does a yeoman's job of resisting corrosion in most exterior environments, and it has a wide connection hole for ease of use with carabiner clipping. It is even possible to install two carabiners at once because of the generous width of the hole. The hanger won't turn while the anchor is being installed; the textured back prevents that. This hanger is also thick enough to prevent the connectors from wearing down. These Petzl stainless hanger bolts are also available as 12mm or 10mm diameter bolts. The additional options of 10 mm bolts and 12 mm bolts give you the flexibility to suit your needs.
Each stainless hanger bolt resists corrosion outdoors and provides a secure, dependable connection. Combined with the quality hanger and nut, these 316L stainless steel bolts are easy to work with and will provide dependable durability no matter what the task. A special anti-rotation system provides no-hassle installation, and the large hole in the hanger makes it easy to clip carabiners to it.
