The Black Diamond RockLock Twistlock-Carabiner is a large HMS screwgate carabiner brilliant for belaying and rigging.

Now hot forged for an overall lighter-weight construction without compromising on strength.

The Twistlock design is easy to use one handed and is idiot proof; if the gate is shut then the carabiner is locked. The Rocklock Twistlockis an ideal for when you need a large HMS for rigging andfor fast secure attachments, such as on Via Ferrata.
