Buying Guide

Lock type matters

Choose screw-locks for simple, field-serviceable security or auto-locks for faster, hands-free closure when belaying or hauling

Check kN strength ratings

Look for major-axis ratings around 20–25 kN for general climbing use and verify UIAA or equivalent certification when available

Pick the right shape

D-shaped carabiners concentrate load along the spine for higher strength, while other shapes may be better for rigging or multi-directional loading

Material and weight tradeoffs

7075 or aerospace-grade aluminum offers high strength-to-weight; steel adds abrasion resistance but increases weight

Gate and nose design

Smooth gates and snag-free noses reduce rope and hardware hang-ups; hot-forged bodies improve durability and consistent tolerances
