DMM Ceros Locking Carabiners


The Ceros minimizes the risk of cross loading. Easy to operate with one hand, and able to locate on the belay loop in a single movement, the Ceros is intuitive to use and simple to rack. Correct orientation is achieved with an internal wiregate that keeps the Ceros captive on a belay loop, and a horn which prevents assisted braking devices moving onto the carabiner’s spine. Full section top bar gives smooth rope control and resists wear.


  • Directional belay carabiner designed to ensure optimum orientation when belaying

  • Pronounced horn prevents belay and other rope control devices cross loading the carabiner

  • Optional captive bar allows installation in tamper proof systems
