Black Diamond Magnetron Carabiner

Purchase on Amazon (Silver)

Tired of messing with twistlocks, screwlocks, or, worse yet, no-lock carabiners? This innovative design employs magnetic attraction to a steel insert inside the carabiner nose to keep two independent arms locked in place, each of which must be individually depressed before the gate can be opened — and once it is, opposing fields repel the arms to ensure reliable operation.
