Notch Modified D Steel Carabiner – Triple-Action Auto Lock

The Notch Modified D Steel Carabiner is a heavy-duty professional connector designed for arborist, technical rescue, rope access, work-at-height, rigging, and industrial applications requiring high strength and a large working area.

The modified D profile provides a larger gate opening than a traditional oval carabiner, making it well suited for connecting larger equipment, ropes, slings, anchors, and other compatible hardware. The steel construction provides exceptional durability for demanding professional applications.

This configuration features the Triple-Action Auto Lock gate, providing a three-stage locking action for increased security against unintended gate opening. The 23 mm gate opening provides additional clearance for larger components.

The connector provides a 53 kN major-axis strength, 16 kN minor-axis strength, 18 kN open-gate strength, and a 16 kN / 3,600 lb gate rating. It is certified to CSA Z259.12-16 and EN 362:2004/B requirements.
