The lock body is constructed from lightweight anodized aluminum and features a 5-pin tumbler rekeyable cylinder. It operates on a keyed-different, master-keyed configuration, meaning each lock has its own unique operating key while also accepting a designated master key (428M). The shackle measures 1.5 inches in height and 1 inch in diameter. The blue color coding supports visual identification of authorized personnel or departmental lock assignments, a common practice in LOTO programs.\u003c\/p\u003e\u003cp\u003eThis padlock is suited for energy isolation points on electrical panels, valves, circuit breakers, and equipment lockout stations in industrial plants, utilities, and commercial facilities. It is commonly installed by electricians, millwrights, and safety professionals administering LOTO programs compliant with OSHA 29 CFR 1910.147. The master-keyed feature makes it practical for safety supervisors who require override access across multiple individually keyed locks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAnodized aluminum body — lightweight and corrosion resistant\u003c\/li\u003e\n\u003cli\u003e5-pin tumbler rekeyable cylinder for flexible key management\u003c\/li\u003e\n\u003cli\u003eKeyed different with master key compatibility (master key 428M)\u003c\/li\u003e\n\u003cli\u003eBlue color coding for visual LOTO program identification\u003c\/li\u003e\n\u003cli\u003eShackle dimensions: 1.5 inches x 1 inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with master key 428M.
