MBS (16 kN vs. 12 kN), meets ANSI\/ASSE Z359.12-2019 and CAN\/CSA Z259.12-16, and weighs slightly more (100g vs. 84g). The trade-off is a smaller gate opening (16mm vs. 22mm).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need the ANSI version for arborist work in the US?\u003c\/strong\u003e\u003cbr\u003eIt depends on your employer's requirements and applicable regulations. ANSI Z133 is the arborist-specific standard — verify which certifications your safety program requires before purchasing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the gate opening smaller on the ANSI version?\u003c\/strong\u003e\u003cbr\u003eYes — 16mm vs. 22mm on the standard Locksafe.
