Keep your hardware in place. The Petzl CAPTIV ensures the carabiner loads along the major axis, limiting the potential to cross-load. A couple of small screws secure the CAPTIV to the carabiner bar. Moulded from a robust nylon material. Ideal for use with a work positioning lanyard. The Petzl CAPTIV is compatible with William, OK, Am'D, OXAN and Rollclip A carabiners. A genuine Petzl part.
