Auto Locking HMS Carabiners from Bailey's

HMS shaped carabiners are great for those who prefer a wider gate opening and more room for rope hitches and accessories. HMS is short for the German word "Halbmastwurfsicherung", which is also known as a "Modified D" carabiner. This category contains HMS auto locking carabiners that have two or more gate locking mechanisms, so they are designed for personal support. All auto locking carabiners listed conform to ANSI Z133-2012 standards. Although auto locking carabiners can be used for rigging, they should never be used for personal support once they have been used for that purpose. We recommend sticking to screw lock carabiners for rigging, just to keep confusion to a minimum. We have listed the different styles of auto locking HMS carabiners we offer below.
