The Phantom is a featherweight at just 42 grams. 24kN major axis and 9kN minor axis strength means the Phantom is strong despite its minimal weight. The locking carabiner that doesn't compromise on weight or strength.
 
Personal Locker
Where weight and size are as important as strength such as on sling runners and for most connection points on belay stances.  In a standard 2 person climbing team, most of your locking carabiners will be personal lockers.
 
Offset D Shape
Encouraging loading along their strongest orientation, D-shaped carabiners force loads towards the carabiner spine.  The offset-D extends the top bar, increasing internal volume for better handling and thick rope compatibility.
 
Hot Forged I-Beam
I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
