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.

RockLock Twistlock

I normally use them for my anchore system, they are durable and don't wear out quick with the rope.

Taiwan

I didn't look hard enough before I ordered. I didn't realize that they were made in Taiwan until I received them.

Killer product

Twist mechanism is easy to work but feels really secure. Lightweight, strong, reliable. Everything is to love!

Nice to have

I like having the extra security of the twist lock on my belay device. The motion is a bit tricky with one hand, but I'll get used to it.

Fast but has increased risk in some use cases

As a gym or TR belay carabiner it’s great for increasing efficiency and safety between laps. However, there is real risk in either the rope or a belay loop briefly rubbing the gate causing it to open. I have seen the gate open while 3 pitches up due to contact with the rope while pulling it for rappel. I would recommend this for gym or TR use but not for multi-pitch or alpine use where complex rope management and awkward belays are more common.

Easy to Use

My only gripe on this carabiner is that it is almost too easy to open. I ran the rope past the lock in the gym and was able to get it to open without touching it with my hands, but I was not able to do this to get the rope back out (thankfully). Super fast and easy to use.

Not ideal

Without an additional locking mechanism such as a button, the twist lock is not as safe as it could be. Good for top rope belaying in a gym, but not much else.

Great Carabiner

Well made Carabiner. No surprise I’ve purchased many items from Black Diamond and had good experiences with all of them.
