Key Features Explained

The gate opens by twisting the barrel against spring pressure and is described as locking automatically when released. The D shape and locking mechanism describe the connector’s design, but do not establish compatibility with a particular rope, harness, anchor, or system.

What to Compare Before Buying

  • Application and compatibility: Check that this exact model is suitable for the intended climbing system and compatible with the equipment it will connect.
  • Rating and certification: Compare the stated 27 kN rating and listed UIAA certification with the requirements for the specific application. A rating alone does not determine suitability.
  • Dimensions and quantity: Check the listed 4.6 x 2.8 x 0.7 in dimensions and confirm that one carabiner is the quantity needed.

Important Limitations

The stated strength is not a safety margin or a guarantee of suitability for every load direction or use. Follow the manufacturer’s instructions for selecting and using the carabiner; the locking feature alone does not confirm that a connection is appropriate.

Before You Decide

Confirm the exact model, application compatibility, required rating, dimensions, and one-item quantity for your intended use.
