Black Diamond’s Magnetron Carbiners are locking carabiners that utilize magnets not twistlocks or screwlocks on the gates. Magnetic attraction to a steel insert in the carabiner nose keeps two independent arms securely locked.
Locking arms must be individually depressed before the gate can be opened. Once open, opposing magnetic fields repel the arms to ensure smooth and reliable gate operation. To be released July 2012.
