The body measures 1-3\/4 inches wide and is constructed from layered laminated steel, providing high resistance to cutting and impact. The hardened steel shackle measures 5\/16 inches in diameter, 3\/4 inches in width, and 15\/16 inches in height, delivering a tight clearance profile that limits tool access. A 5-pin tumbler cylinder adds pick resistance. This padlock is specified by facilities managers, contractors, and security professionals who need multiple locks sharing a single key.\u003c\/p\u003e\n\u003cp\u003eThis padlock is suited for securing equipment enclosures, gate hasps, tool storage, job-site lock boxes, and chain barriers in both residential and commercial settings. The keyed-alike configuration makes it practical when a single worker or crew needs to operate multiple locks without carrying separate keys. Its compact shackle clearance makes it a strong fit for applications where exposed shackle length is a vulnerability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLaminated steel body construction for high cut and impact resistance\u003c\/li\u003e\n  \u003cli\u003eHardened steel shackle, 5\/16 inches in diameter with 15\/16 inches of clearance\u003c\/li\u003e\n  \u003cli\u003eKeyed alike — multiple units operated by the same key\u003c\/li\u003e\n  \u003cli\u003e5-pin tumbler cylinder for enhanced pick resistance\u003c\/li\u003e\n  \u003cli\u003eCompact shackle profile limits prying and tool attacks\u003c\/li\u003e\n  \u003cli\u003eMaximum security padlock classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a keyed-alike replacement or add-on padlock compatible with standard hasp, chain, and latch hardware accepting a 5\/16-inch shackle diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no tools beyond confirming the hasp or latch hardware is compatible with the shackle dimensions.
