High Strength Gates 3,600lbs M.B.S.
ANSI Z359.12 Requirements for Snap Hooks and Carabiners
The ANSI Z359.12 calls for significant increases to these critical requirements with the intent to improve overall user safety. The new standard increases the minimum gate face and side load requirements to meet or exceed 3,600 lbs (16kN) which is more than 10 times the original standard. This standard will also require that connectors with non-integral eyes have minor axis gate strength of 3,600 lbs (16kN). In addition to the physical testing requirements of the new standard, the gate of the connector must be marked with the load rating and the body of the connector is to be marked with a major axis load rating. Non-integral connectors are to be clearly marked with ANSI Z359.12.
Note: This voluntary standard only applies to fall arrest equipment used in general industry and does not apply to the construction industry. The construction industry has their own set of standards.
