The Boa is hot forged from 14mm aluminium bar to give it the 30kN major axis rating required for rescue loads. The massive curved basket copes with even the busiest rigging set up and still allows devices to settle comfortably. The impressive size and ergonomics ensure it can be operated by even the largest hands with the chunkiest of gloves.

DMM's patented Taperlock closing mechanism increases gate push-in and cross gate strength using a special flared profile on the nose of the carabiner, as well as allowing a snag free connection for your ropes, slings and devices.


  • Large HMS shape big enough to fit multiple ropes or connections
  • 14mm loading surface for increased wear resistance
  • Keylock clean nose for snag free connection
  • Available with a Durolock gate
  • Easy to use with gloved hands
