Alternatives

  • Screw-lock vs. auto-lockAuto-lock reduces the chance of an open gate; screw-lock is simpler.

Maintenance notes

  • Retire after a significant fall or impact; keep gates clean and closing freely.

Buying considerations

  • Only load-rated (not accessory) carabiners belong in a safety system.
  • Match the shape to the job — HMS for belay, D for strength.

⚠️ Safety notes

  • Hardware-store carabiners are not rated for people. Use only certified connectors, correctly loaded, within a trained system.
