[Black  & Red One Size]

If mutation is the next step in evolution, then the Black Diamond GridLock Screwgate Carabiner might be a glimpse at a future in which climbers have super-sticky hands and live on high-alpine cliffs. Black Diamond designed this screwgate with an ergonomic belay loop to prevent cross-loading, a keylock nose for snag-free unclipping, and an I-beam construction for a lighter feel.
