Double-locking Carabiners: ANSI Gate

Many climbers choose carabiners that meet the ANSI z359 standard for Fall Arrest Systems. This standard puts a strength requirement on all axes of the carabiner, including when side-loaded, of at least 3,600 lbs (16 kN). The carabiner and gate must have this rating marked, and the body must have this rating and the minor axis load rating.
