Cypher D Locking Carabiner

Steel is significantly more durable and resistant to wear than aluminum, making it the better choice for high-use industrial environments, top-roping, or situations where the carabiner will be in constant contact with steel cables or abrasive surfaces. While heavier, it offers superior longevity and strength.

The D-shape is engineered to shift the majority of the load onto the carabiner's spine, which is its strongest axis. This design ensures optimal load distribution and keeps the carabiner stable during use.

The screw gate requires manual locking and unlocking, which is reliable but slower to operate. The three-stage auto-locking gate automatically locks shut every time it closes, providing an extra layer of security that is ideal for high-frequency use or situations where you cannot risk forgetting to lock the gate.

Yes. The keylock nose design eliminates the hook-and-notch interface found on traditional carabiners, creating a smooth, snag-free surface that prevents the gate from catching on ropes, slings, or your harness.

Yes, it is certified to CE EN12275:1998-B standards, which covers mountaineering equipment. However, keep in mind that at 265 grams, it is heavier than standard aluminum climbing carabiners, so it is best suited for heavy-duty applications like top-roping or industrial work rather than long-approach alpine climbing.
