Climbers might be a bodacious bunch, but when it comes to climbing safety most don't mess around. Edelrid's HMS Strike Triple FG Locking Carabiner automatically locks itself ever time you let go of the gate for the enhanced security climbers look for. That doesn't mean you shouldn't double- and triple-check your belay device before you tell your climber to climb on. Edelrid added a spring bar to this carabiner to prevent cross-loading for an even safer belay.
