The Phantom weighs 41.5g and is the lightest keylock screwgate biner in the world.
It also is very functional and very strong with a major axis strength of 23kN and a gate open strength of 9kN.
The remarkable thing is that we could have made it even lighter if we were willing to compromise on it's strength and safety, but we are not willing to produce an offset D carabiner with a gate open strength of less than 9kN. If we were to accept a gate open of 7 kN we could have kept the same size and got down to 20g. However we do not believe that 7kN gives enough safety margin.
The same thought process is applied to the carabiner gate and barrel - we could have reduced the wall thicknesses to drop the weight down even further, but we have kept the same high strength 7075 components that we use on a lot of our other I Beam carabiners. This barrel has a massive push-in strength.
We have achieved all this by using the same special alloy that we use on the Phantom wiregates and using our knowledge of forging /heat treating aluminium.
All of our standard DMM features are present - smooth steep internal radiuses to minimise the chances of the carabiner hanging up or of the carabiner being loaded badly, fully anodised finish and an internal rope groove.
The Phantom series of carabiners are the ultimate range for traditional and alpine climbing.
