Buying Guide

Check gate and lock type

Choose screw-lock for simple manual security or auto-lock for hands-free closure and added safety when clipping under load

Verify strength ratings

Look for major-axis ratings around 25 kN and clear UIAA or EN markings to ensure suitable strength for climbing use

Prefer D-shaped geometry

D-shaped carabiners concentrate load on the spine for higher strength and better rope alignment on belays and protection

Consider material and weight

Aluminum 7075 offers excellent strength-to-weight; steel variants are heavier but better for repetitive rope wear or fixed anchors

Inspect gate smoothness and keylock

Smooth gate action and a keylock or snag-free nose reduce hang-ups when clipping and unclipping under stress
