Totally re-designed for 20009 the ever popular Belay Master continues to set standards for safety and design with a lighter, stronger I-beam body, keylock nose and greater internal volume. The Belay Master is an HMS screwgate carabiner that comes with a patented, integral plastic clip to increase safety of belay system. The clip can only be locked into place when the screwgate barrel is in the locked position, thus providing a fail safe check that the carabiner is securely closed. The clip also prevents the carabiner from rotating in the belay system and becoming cross loaded.
