Black Diamond Gridlock Screwgate

The Black Diamond Gridlock Carabiner is a unique belay carabiner which solves the problem of the crab rotating on your belay loop and being cross-loaded in the event of a fall. This is a potential point of weakness since carabiners are inherently less strong on their minor axis. The Gridlock solves this problem by adding a spur to the gate which makes it almost two carabiners in one. First you clip the Gridlock into your harness with the main carabiner eye. Then you pull the carabiner to make your belay loop captive in the smaller eye of the crab. Finally you clip in your plate and rope and belay as normal.

The Gridlock is especially useful for inexperienced climbers or those who teach groups, as it allows you to check belay systems at a glance, eliminating a potential hazard.
