Metolius Locking Carabiner

Steel is significantly more durable and resistant to wear than aluminum, making it the better choice for high-friction, repetitive tasks like top-roping or setting up permanent anchors. While heavier, it offers superior longevity and structural integrity in demanding environments.

The screw-locking version requires manual twisting to secure the gate, which is often preferred for its simplicity and reliability in dirty or icy conditions. The auto-locking version closes automatically, providing an extra layer of security against forgetting to lock the gate, though it may require more attention to ensure it has fully engaged.

At over 200 grams, this carabiner is quite heavy for standard lead climbing where weight management is critical. It is best suited for big wall setups, hauling, or as a dedicated anchor component where strength and durability are prioritized over weight savings.

A 40 kN rating indicates the carabiner can withstand significantly higher forces than standard aluminum climbing carabiners, which typically range from 22 to 26 kN. This high threshold provides a substantial safety margin for heavy-duty anchoring and multi-person loads.

Yes, these carabiners meet both CE and UIAA standards, ensuring they have been rigorously tested and approved for use in climbing and mountaineering applications.
