The Petzl OXAN is a high-strength steel carabiner designed for use in difficult environments. The oval, symmetrical shape allows optimal loading of the carabiner when setting up anchors or connecting to metal structures. Secure automatic TRIACT-LOCK system. OXAN can be connected to the CAPTIV bar to favour positioning of the carabiner along the major axis, to limit the risk of it flipping and to keep it integrated with the device.
