Versatile and sound, the EDELRID HMS Magnum Triple Locking Carabiner is in our rack for cragging and big wall climbing alike. I-beam construction keeps weight down without sacrificing strength, and a wider, rounded inner radius reduces the wear on our rope. Equipped with a large gate opening and rope basket, this locker accommodates more than one rope and device for anchor and haul systems, while its auto-lock gate gives us instant security.
