DMM Belay Master 2 Screw Gate Carabiner-Silver. There is potential for the biner to flip into a bad alignment and for cross loading to occur. With this in mind DMM came up with a special clip that once locked in position prevents cross loading occurring by holding the biner and belay device in the correct alignment. There is another advantage too: the clip can only be locked if the Screwgate has been properly closed first. DMM has given the Belay Master 2 Screw Gate Carabiner a Taper Lock nose a special flared profile on the nose of the biner which significantly increases the side loading strength of the gate. The belay Master 2 is also surprisingly light. So there you have it one of the safest belay biners ever made and a fool proof set up that has proved very popular with climbing walls and outdoor centers.
