This lightweight locking biner is constructed using an ISO Cold Forging process for an extraordinary strength-to-weight ratio. Locking mechanism provides security against accidental opening, and locks to the gate, not the frame, to prevent jamming. Classic D shape carriers the loads off-center, toward stronger, non-gated side. Hooded gates offer smooth rope-bearing surfaces. Tapered nose for increased strength and spin rivets for smooth snag-free gate surfaces. Anodized coating wont flake off like paint, helps protect against corrosion and allows you to sort and identify gear easily. CE certified.
