Lots of karabiners have been claimed as the lightest screwgate in the world. The Phantom actually is, at a whole 41g. What is more, DMM's superb I-beam technology has ensured that the gain in weight has not resulted in a low strength rating (unlike some other super-light karabiners). The phantom screwgate is slightly larger than the phantom wiregate - only slightly smaller than a conventional screwgate.
