These 12-millimeter bolts are made of HCR 904 (high-corrosion resistance) stainless steel, making them the perfect choice when working in an area that experiences extensive corrosion. Designed for use with Petzl's HCR 904 hangers, this is one of the strongest units available. It's easy to use, and thanks to the large attachment hole, you can install two thick carabiners to one anchor. The thick construction and rounded edges along the attachment holes work to protect the connectors from wear and tear. The hanger features an anti-rotation system to prevent the hanger from turning while installing the anchor. It has a textured back so it doesn't slip off the structure, which is also helpful when the anchor is heavily side-loaded. Shop OmniProGear's huge selection.
Petzl anchors (hangers and bolts) use different types of steel to adapt the anchor to the
environment in which it is used:
• HCR 904 (High Corrosion Resistance) stainless steel, designed for ultra-corrosive
Featuring a large attachment hole, Petzl
hangers facilitate clipping carabiners and
allow two carabiners to be installed, even
thick ones, in the same anchor.
Preventing connector wear
Petzl hangers are characterized by high
thickness, and rounded edges on the
attachment holes. This construction
minimizes wear on connectors,
regardless of their material composition.
Hanger anti-rotation system
Petzl hangers are textured on the back
side that is in contact with the structure
(concrete, rock...). This helps prevent the
hanger turning when the anchor is being
installed, or when it is heavily side-loaded
