Edelrid Pure Screw III

The H-profile design allows the carabiner to be incredibly strong while remaining lightweight. By distributing material only where it is needed for structural integrity, you get a durable piece of gear that won't weigh down your harness.

Yes. The keylock nose design eliminates the hook found on traditional carabiners, which prevents the gate from catching on your rope, slings, or harness gear loops during clipping and unclipping.

The generous rope contact area helps distribute the force of the rope across a wider surface. This reduces localized friction and wear, meaning the metal will last longer even with frequent use.

While it is a versatile locking carabiner, its size and shape are best suited for general tasks like building anchors, attaching personal retention systems, or clipping into gear. If you are looking for a dedicated belay carabiner, you might prefer a larger HMS-style shape.

The offset D shape is designed to direct the load toward the stronger spine of the carabiner. This shape also provides a larger gate opening compared to a symmetrical D, making it easier to clip ropes or webbing.
