The solid brass body measures 1-31\/32 inches high and 1-3\/4 inches wide, making it compact enough for standard hasps, cabinets, gates, and toolboxes. The 5\/16-inch diameter shackle provides a balance of cut resistance and flexibility for everyday lockout and access-control tasks. Keyed Different means each lock ships with its own unique key, suitable for installations where individual keying is preferred over a master-key setup.\u003c\/p\u003e\n\u003cp\u003eThis padlock is well suited for HVAC technicians, electricians, plumbers, and other trade professionals who need reliable lockout\/tagout hardware or general-purpose security. The brass construction resists corrosion in humid or outdoor-adjacent environments such as mechanical rooms, rooftop equipment enclosures, pool equipment areas, and utility panels. The compact body profile fits standard commercial hardware and lockout hasps without interference.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid brass body resists corrosion and weathering in demanding service environments\u003c\/li\u003e\n  \u003cli\u003eKeyed Different configuration — each lock operates with its own unique key\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch shackle diameter with 29\/32-inch shackle width for standard hasp compatibility\u003c\/li\u003e\n  \u003cli\u003e2-7\/16-inch shackle clearance accommodates a range of hasp and chain thicknesses\u003c\/li\u003e\n  \u003cli\u003eCompact body at 1-31\/32 inches high and 1-3\/4 inches wide fits most standard lockout points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service brass padlock for use with conventional hasps, lockout\/tagout stations, gate latches, and cabinet hardware requiring a 5\/16-inch shackle diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this padlock does not require specialized tools. Verify that the hasp or receiver opening accommodates a 5\/16-inch shackle diameter and that the shackle clearance of 2-7\/16 inches is sufficient for the application before installation. For lockout\/tagout use, follow OSHA 29 CFR 1910.147 procedures and ensure the lock is applied only after the energy source has been fully isolated. Do not force the shackle into undersized hardware, as this may damage the locking mechanism.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Height\u003c\/strong\u003e: 1-31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShackle Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShackle Width\u003c\/strong\u003e: 29\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShackle Clearance\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeying\u003c\/strong\u003e: Keyed Different\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MASTER LOCK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6840LJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER LOCK","offers":[{"title":"Default Title","offer_id":51541486534962,"sku":"6840LJ","price":45.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc124f96bf359a0b8a7219d866604e19.jpg?v=1785877553","url":"https:\/\/voomisupply.com\/products\/master-lock-6840lj-brass-padlock-keyed-different","provider":"Voomi Supply","version":"1.0","type":"link"}
