Aluminum alloy ultralight wide-opening D-shaped carabiner

A high-performance aluminum alloy large-gate D-shaped carabiner designed specifically for sport climbing, lead climbing, and multi-pitch climbing. The body is precision-crafted from 7075 aerospace-grade high-strength aluminum alloy, with a single carabiner weighing only about 50g, offering an excellent strength-to-weight ratio and durability.

The contact surfaces between the carabiner body, the rope, and the bolt hanger have been significantly widened and optimized. This not only effectively reduces rope friction and extends the service life of the main rope, but also significantly improves the wear resistance of the carabiner. The carefully calibrated large-gate design, combined with the Keylock nose structure, ensures smooth, snag-free operation whether clipping into hangers or rapidly passing ropes.

Key Features

• Aerospace-grade 7075 Aluminum Lightweight Construction: Weighs only about 50g per unit while maintaining a high 23kN strength, significantly reducing gear load.

• Widened Contact Arc for Rope Guidance: The contact area for ropes and hangers is widened and thickened to optimize sliding smoothness, reduce groove wear, and protect the rope sheath.

• Large Gate for Fast Rope Clipping: Features extra-wide 25mm (straight) and 24mm (bent) gates, allowing for more precise and agile operation even with gloves or during blind clipping in extreme conditions.

• Keylock Snag-free Nose: The gate area utilizes a notch-free nose structure, completely eliminating the issue of snagging on hangers, slings, or ropes during clipping or unclipping.

• Dual CE / UIAA Certification: Complies with European CE EN 12275:2013 and UIAA 121:2016 international mountaineering safety standards, providing top-tier protection.
