High Quality 10cm-12cm Bungee Safety Hook

Safety hook, also called the main lock, mountaineering buckle, safety buckle, equipment buckle and so on. Safety hook standards follow NFPA 1983 safety rope and equipment standards used in emergency rescue services, and the product should indicate whether it is a technical product (light product) or a general purpose product based on design load and performance requirements. The standard allows manufacturers to indicate the rated minimum breaking strength of the product at MBS or higher, but does not exceed the calculated value of 3σMBS based on the latest experimental results. Some manufacturers indicate the minimum performance requirements required by NFPA on the product and provide the test results on the label or product manual. Other manufacturers simply indicate on their equipment a value of 3σ MBS based on the latest experimental results.

In ANSI/ASSE Z359.12 fall protection guidelines, the strength requirement for safety hooks is 5,000lbf (22.2kN). Because the safety hook may strike or slip through the load when a worker equipped with a fall brake system falls, the standard requires a strength of 3,600lbf (16kN) to push forward and sideways and close the safety hook opening.
