Cypher D Locking Carabiner

The hardened, zinc-plated steel construction offers significantly higher durability and wear resistance than aluminum. This makes it ideal for high-friction environments, such as top-roping or industrial applications, where the carabiner will be subjected to repeated rope movement or heavy loads.

The keylock nose design eliminates the hook found on traditional carabiners, which prevents the gate from snagging on ropes, webbing, or gear loops. This ensures a smooth, snag-free clipping and unclipping process every time.

Choose the screw gate if you prefer a simple, reliable mechanism that is easy to operate with gloves. The three-stage auto-locking version is the better choice for high-security applications where you need to ensure the gate locks automatically every time it closes, reducing the risk of human error.

Yes, it is certified to both CE EN12275:1998-B for climbing and CE EN362:2004-M for industrial use. Its 50 kN major axis strength makes it a robust choice for heavy-duty rigging, rescue operations, and demanding climbing setups.

This carabiner weighs 265 grams. Because of its steel construction and high strength rating, it is significantly heavier than standard aluminum climbing carabiners, so it is best suited for applications where durability is prioritized over weight savings.
