Load rated stainless steel carabiners with eye. Each hook individually stamped with break load and features the patented Kong Key Lock System. Complies with DIN 5299 Stainless Steel AISI 316 Arthur Beale says:The Kong Key Lock system is a massive improvement on the usual carbines which normally have a sharp, flesh tearing and rope snagging, notch near the opening. These Kong carbines have a very smooth inside face so you can say goodbye to trashed ropes and pools of blood on the teak decks.
