The operator belt has a solid stainless steel, low profile buckle that has a 6000lb rating. With a quick click of a carabineer, the operator belt can be used for support in extreme emergency climbing situations (only to be used in emergencies, the operator belt is not designed as a climbing harness). The durable nylon webbing locks securely in the belt buckle and is additionally locked with a Velcro® locking system.
