Best Overall Locking Carabiner
Red stripe to indicate biner is unlocked
Easy-to-open screw lock
Lacks durability of other carabiners
The Editors' Choice Award goes to the Petzl Attache
. It was the only carabiner to score well in every category and the only light carabiner to excel in the overall scores. This carabiner performs exceptionally, no matter the situation. Its main drawback is the price.
