The lightweight Omega Pacific Omegalite 4.0 Screwgate locking carabiner is constructed using an ISO Cold Forging process for a high strength-to-weight ratio. Locking mechanism provides security against accidental opening and locks to the gate, not the frame, to prevent jamming. ISO Cold Forged design puts more aluminum exactly where its needed to render the strongest design possible for a carabiner of its size and weight. Climber-friendly shape is easy to hold and leaves access to the gate clear for easy clips. Special buy.
