RockLock Twistlock Carabiner

Black Diamond's RockLock Twistlock Carabiner automatically locks after you set the belay for your climbing partner. That means no more looking down and noticing an unlocked gate after you told your partner to climb on. Black Diamond also designed this locker with a keylock nose for snag-free unclipping, a curved spine for a larger gate opening, and a square hinge to hold your belay device in place.

Twist lock review

Fantastic Carabiner!! My main use for these is on top rope solos as I don’t want to have to twist a screw gate. Very versatile piece of equipment!!

Color confusion

Nice easy action. Only wish the color of the screw was different so it’s easier to tell this and my screw lock apart

Buy once, cry once!

Yes, there are less expensive options, but these are worth the extra money. The auto lock feature works flawlessly, the the large, textured gate is easy to use even when wearing mittens or gloves. Purchased these to use in teaching Low Angle Rescue courses for the NSP.

THE standard for a belay device carabiner

My title says it all, this has been my standard belay device carabiner for the past twenty years. Love it.

Wanted a different model

I love my new carabiner. I actually thought I was buying the less expensive model, which is what I originally wanted, but I had no way of actually knowing not being a rock climber and everything. I personally bought these just lug around my keys and I love the twist lock

Good stuff

I have multiple of these Carabiners and use them primarily for my belay devices. They are reliable and easy to work with.
