Black Diamond AirLock 2 Twist Lock Carabiner (Cosmetic 2nd)

Large but light, the Airlock2 Twist by Black Diamond is designed to work smoothly with any belay system, whether it�s an ATC, Super 8 or Munter hitch. A large internal volume holds all the bulky knots, harness webbing and stacks of runners you could ever need. Available in both Twistlock and Screwgate versions (both of which can be operated with one hand), the Airlock2 is simple, easy to operate and won�t lock up under body weight.
