DMM's Phantom Screwgates are available at Basecamp.

The world's lightest locker at 41.5g! The remarkable thing is that DMM could have made the krab even lighter had they been willing to accept a gate open strength of less than 9kN by reducing the wall thicknesses, but they didn't want to compromise on safety. The Phantom even beats Wild Country's innovative Neons with their 43g and an 8kN open gate rating!

In short, a full 23kN offset D keylock carabiner with DMM's I beam construction at 41.5g and a 9kN open gate strength. A clear winner in our eyes.
