Edelrid Bulletproof Screw ECO (Offset-D) – compact, durable screwgate biner

The Bulletproof Screw ECO (Offset-D) is a small, robust screwgate carabiner designed for hard everyday use. A steel insert at the apex helps prevent premature wear and avoids burrs or sharp edges over time—ideal for personal protection use, such as clipping into a belay anchor.

Part of Edelrid’s ECO line, it’s particularly sustainable because it’s non-anodized, reducing processing and chemical treatments while keeping the same certified performance. The H-profile body keeps weight low, and the Keylock nose ensures smooth, snag-free handling.

• Non-anodized ECO finish for a lower-impact production choice
