Petzl Ange L Carabiner. The new generation ANGE L carabiner represents the middle ground between the traditional gate carabiner and the classic wire gate carabiner. It combines the fluidity of the spring gate with the lightness of the wire gate system. Petzls MonoFil Keylock technology and the H-profile make the ANGE L carabiner weigh a light 34 grams and provide an optimal weight-to-strength ratio. So it is particularly suited to users looking to reduce weight while keeping the functionality of a standard size carabiner. The shape of the nose is designed to optimize clipping and unclipping.
