This OSHA Safety Lockout/Tagout (LOTO) Padlock features an Extended Long Metallic Shackle (76–80mm) — specifically engineered for applications where a standard 38–40mm shackle cannot reach the lockout point. The longer shackle provides the additional clearance needed to secure thick valve handles, large hasps, oversized circuit breakers, pipes, chains, and multi-lock group lockout devices.
Equipped with a Different Key (DK) System, every padlock in the set carries its own completely unique key — no two locks can be opened by the same key. This guarantees strict individual lock ownership and accountability, a fundamental requirement under OSHA LOTO regulations for protecting workers during hazardous energy isolation.
Fully compliant with OSHA CFR 29 Part 1910.147 for the Control of Hazardous Energy.
