Petzl's standard steel anchors include a Coeur steel hanger, bolt and nut, and are created for use in low-corrosion environments. Petzl's wide, ergonomic connection hole makes for easy clipping, and the hole is wide enough to install two carabiners at once. The hanger's thickness and the rounded edges of the connection hole help prevent wear and tear on the connectors. The hanger has a textured back as part of its anti-rotation system. The texture offers grip and prevents the hanger from turning during installation or when the anchor is heavily laterally loaded. It's available in 10-millimeter and 12-millimeter bolt sizes. Certifications include EN 795 A1 and EN 959. OmniProGear features a huge inventory and is always first with the latest items.
