The Shield features the patented wirelock clean nose that stops the biner from being snagged when clipping or unclipping. The clean nose also means there is no notch on the nose that can snag on bolts or wires and allow the biner to be loaded away from the spine.
The strongest of DMM's wiregate biners, the Shield features I beam technology to keep the weight down — just what's needed when trying to onsight your hardest sport climbs. A strong 10 kN open gate strength means however much abuse this biner takes, it will be up to whatever task you throw at it. The wire gate keeps weight to a minimum while providing an easy clip with minimum chance of freezing or gunging up.
