Am'D Twist Lock Carabiner

The Keylock Nose design eliminates the hook or notch typically found on carabiners, allowing for smoother clipping and unclipping. This feature reduces the chance of snagging on ropes or gear, making it especially useful in climbing situations where quick access is crucial for safety and efficiency.

The D Shape of a carabiner optimally distributes weight and strength, making it ideal for connecting to a belay system or holding gear. This design enhances load-bearing capacity, which is vital for safety and performance during climbing activities.

Screw-Lock: Requires manual screwing of a sleeve over the gate to secure it. Ball-Lock: An automatic locking mechanism that uses a ball to secure the gate when closed, requiring a specific action to open. Twist-Lock: Allows for quick access by twisting the sleeve to lock or unlock the gate, combining ease of use with safety.

Major Axis Strength refers to the strength of the carabiner when force is applied along its longest axis. A major axis strength of 27kN indicates the maximum force the carabiner can withstand before failing, which is crucial for ensuring safety during climbing and other high-stress activities.

Open Gate Strength indicates how much force a carabiner can handle when the gate is open. With an open gate strength of 7kN, it’s important to consider this factor, as carabiners can experience forces even when not fully closed, especially in dynamic climbing situations. Understanding this helps ensure you choose a carabiner that meets safety standards.

It is not recommended to use a carabiner with a lower Major Axis Strength for climbing, as safety is paramount. Always choose a carabiner that meets or exceeds the required strength ratings for your specific climbing activities to ensure maximum safety and performance.
