DMM Alpha Light Carabiner

Ultra lightweight, clean nosed wire gate carabiner for trad and alpine climbing. Keep the weight down without sacrificing strength
It’s not easy improving on a super lightweight biner like the Phantom, DMM pulled it off when they designed the Alpha Light.

They wanted all the weight advantages of the Phantom, but with better handling and a bigger gate opening.  They created the kinked the backbone to increase the gate opening and put a grooved pattern on the outside of the biner under the natural holding positions.

The functionality improvements did not end there though – a clean nose design was also added to reduce snagging when clipping or unclipping.
