CMC DNA Steel Carabiner (NFPA G Rated)

The DNA Carabiners are unique “helical-shaped” connectors with a twisted carbon steel body and circular bar. This twist enables 90° rotation of any connected device for optimal alignment and offset load management. Ideal for use with descenders, rope clamps, progress capture devices, fall arresters, and the Double Clutch. When used in the Double Clutch TTRS kit, the DNA optimizes the Clutch handle alignment to allow a single operator to manage both Clutch handles for simultaneous twin tension control.



These Carabiners have a durable carbon steel construction with high tensile strength and an auto-locking gate that provides the safety of 3 movements to open: lift, turn, and push. Now available in gray with a new Zinc-Nickel treatment that provides double corrosion resistance from the prior black plating (test carried out in salt spray in accordance with UNI EN ISO 9227), greater scratch resistance, longer life, more uniform and modern finish, and less friction on cords and textile devices.
