Edelrid HMS Bulletproof Carabiner

The steel insert is located at the vertex where the rope runs, which is the primary point of friction. By using steel here instead of aluminum, the carabiner resists grooving and premature wear, significantly extending its lifespan compared to standard aluminum carabiners.

It requires a specific three-step motion—slide, twist, and pull—which can take a moment to get used to. While it is less convenient than a screw-gate, it provides an essential layer of security that prevents accidental opening, making it worth the extra effort for belaying.

The H-profile design is primarily about efficiency; it puts metal only where it is needed for strength, which keeps the weight low without sacrificing durability. In practice, it feels lightweight in your hand while maintaining a robust, secure feel during clipping.

No, the keylock nose is designed specifically to prevent snagging. Because there is no hook on the gate or the nose, it clips and unclips smoothly from bolts and gear loops without catching.

This is an HMS-shaped carabiner, which makes it ideal for belaying and rappelling because of its wide, rounded basket that accommodates various knot types. While it is excellent for those tasks, its weight and triple-lock mechanism make it less ideal for quick-draws or sport climbing where speed is the priority.
