DMM Ceros Screw Lock Carabiner


The Ceros minimises 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.
