Armbury Domain SG D-Shaped Screw-Lock Carabiner

Armbury Domain SG D-Shaped Carabiner

The Armbury Domain SG is a large, lightweight aluminum carabiner with a screw-lock gate, designed for anchors and rigging. Its directional D-shape keeps the load along the major axis, while the wide gate opening and keylock nose make clipping ropes and webbing easier.

Built for practical rigging

When organizing an anchor or connecting rigging components, the Domain SG gives you a roomy 28 mm gate opening and a D-shaped frame designed for strong major-axis loading. A red indicator provides a visible warning when the gate is unlocked, and the keylock nose helps avoid snagging on ropes or webbing.
