The DNA Steel Carabiners feature a unique helical-shaped design that rotates connected devices 90 degrees for improved alignment and load management. Engineered for rescue, rope access, fall protection, and technical rigging applications, the twisted carbon steel body helps optimize the positioning of descenders, rope clamps, progress capture devices, fall arresters, and twin-tension systems.

Constructed from high-strength carbon steel, DNA Carabiners combine exceptional durability with a secure three-action auto-locking gate that requires lifting, turning, and pushing to open. The keylock nose design prevents snagging on ropes, webbing, and anchor hardware, while the wide gate opening simplifies loading and unloading. Finished with a corrosion-resistant zinc-nickel treatment, these carabiners offer improved durability, scratch resistance, and reduced friction when used with ropes and textile devices.
