What is a “Triple Locking Carabiner”?
A Three-Stage buckle is an automatic locking, high-security carabiner that requires the user to complete three actions in sequence to open the carabiner latch, usually:
1. Push the locking sleeve up
2. Rotate the locking sleeve
3. Press the carabiner latch to open
4. Once you’re done, release your finger and the latch will automatically return to its original position and lock.
Additionally, you can watch the video from our A2020TN-1 Silver Three-Segment Carabiner below.
These outdoor 7075 aluminum alloy carabiners are common in rock gyms, climbing schools, industrial rigging, high-rise window washers, mountain rescue, arborist work, and for professionals who do dangerous things on the ground, so this should tell you how safe they are.
Why choose a Triple Locking Carabiner?
High safety: Three consecutive actions significantly reduce the probability of accidental opening, which is a common option for industrial fall protection systems.
Automatic locking: Automatically locks back after release, no need to remember to lock it back manually like a spiral lock.
More stable operation with gloves: The design considers that it can still be operated reliably when wearing thick gloves.
Stronger resistance to misoperation: Not easy to be accidentally opened by ropes, tools, branches.
The purpose of this design is to avoid accidental unlocking as much as possible. Compared with ordinary spiral locks, it can more effectively prevent the carabiner from opening unconsciously and provide stronger protection.
In fact, it is not perfect. The three-step operation takes time for novices to adapt. And it is difficult to operate with one hand, especially when it is high in the air, loaded, and needs to be connected quickly. It is not as flexible as other types.
However, since many novice mountaineering and rock climbing beginners are not so skilled, they are always afraid of forgetting whether the gates of the carabiner are locked, which makes them a good choice for beginner climbers because you can be very sure that it will work as expected.

How to use Triple Locking Carabiner more safely and smoothly?
First, use one finger to push against the carabiner for leverage, then use the thumb and index finger to operate.
Make sure that the buckle door will not get stuck with foreign objects (such as mud, pebbles) to ensure smooth automatic locking
PS: This three-stage carabiner is not suitable for use in places with a lot of mud and sand. It is not very friendly for cave exploration and canyon exploration, which will greatly weaken its performance and advantages. It is also not suitable for ice climbing, as snow and ice may get stuck in them.
When producing this type of carabiner, we usually use 7075 high-strength aluminum and breaking strength test. At the same time, we will provide LOGO customization for different customers needs.

Triple Locking Carabiner is not needed by everyone, but its design provides an extra layer of trustworthy protection. Choosing what kind of climbing hook is not only a choice of function, but also a reflection of understanding of the scene.
