Armbury Hardy AG HMS Triple-Lock Carabiner

Armbury Hardy AG HMS Carabiner

The Armbury Hardy AG is a large, pear-shaped HMS carabiner designed for mountaineering and work at height. Its spacious basket accommodates a Münter hitch or belay device, while the keylock nose helps reduce snagging during connection and removal.

Room to work at the belay

When setting up a belay or managing connections at height, the Hardy AG offers an ergonomic shape and a generous 26 mm gate opening. Hot-forged I-beam aluminum construction balances size, strength and weight, and a lock marking provides a visual warning when the gate is unlocked.
