DMM 30kN Boa HMS - Kwiklock

The DMM Boa HMS Kwiklock Carabiner is a high volume, robust and strong carabiner with a 23mm gate opening. Its asymmetric HMS shape sits naturally in the hand for easy handling, and I-Beam construction means that despite its large size, the Boa is still surprisingly light.

The heavy duty version of the 25kN Boa looks very similar, but is hot forged from 14mm rather than 12mm 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.


  • HMS shaper locking karabiner
  • 14mm loading surface for increased wear resistance
  • Taperlock nose
  • Large gate opening
  • Durable and lightweight
  • Ideal for rigging or belaying; can accommodate multiple knots
  • Easy to use with gloved hands
  • Strong I-Beam construction to save weight (almost 25% reduction)
  • Kwiklock locking systems: Auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor.
