Safety carabiner with screw lock and directional locking.
The DMM Ceros Screwgate carabiners stay in the correct position. The reason for this is the small internal snap gate. This prevents the carabiners from moving out of position when belaying. The screwgate also sits comfortably in your hand and is intuitive to use. Nomen est omen, with the DMM Ceros you minimize the risk of cross-loading.
