Armbury Domain AG D-Shaped Triple-Lock Carabiner

Armbury Domain AG D-Shaped Carabiner

The Armbury Domain AG is a large, D-shaped aluminum carabiner with a triple-lock gate for anchors and rigging. Its directional frame keeps loads along the major axis, while the 28 mm gate opening and keylock nose help make clipping ropes and webbing straightforward.

Strong, practical anchor connections

When building an anchor or arranging rigging components, the Domain AG provides room to clip and a shape designed for efficient major-axis loading. A lock marking offers a visible warning when the gate is unlocked, and the keylock nose helps avoid snagging during handling.
