The padlock features a 4-pin pin tumbler cylinder that provides enhanced pick resistance, making it suitable for locations where unauthorized access is a serious concern. The hardened steel shackle is nickel-plated for corrosion resistance and delivers strong cut resistance. A laminated cadmium rustproof steel case adds durability in outdoor or high-moisture settings. Dual locking levers engage the shackle at two points, increasing resistance to prying attempts. Two brass keys are included. Licensed contractors, facilities managers, and security professionals typically specify this hardware for gates, storage units, and equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThe MLK7D is suited for both residential and light commercial applications where a compact, reliable padlock is required. Common installation scenarios include securing storage lockers, chain-link gates, tool cribs, utility enclosures, and outdoor sheds. The laminated rustproof case makes it an appropriate choice for semi-exposed environments such as covered outdoor storage areas or loading dock equipment. The 40mm body width fits standard hasp openings found on most lockers and gates without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-pin pin tumbler cylinder for improved pick resistance\u003c\/li\u003e\n  \u003cli\u003eHardened steel shackle with nickel plating for cut and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eDual locking levers engage the shackle at two points for pry resistance\u003c\/li\u003e\n  \u003cli\u003eLaminated cadmium rustproof steel case for extended service life in damp or outdoor conditions\u003c\/li\u003e\n  \u003cli\u003e40mm steel body width fits standard hasp openings on lockers and gates\u003c\/li\u003e\n  \u003cli\u003eIncludes two brass keys for immediate deployment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or new-installation padlock for standard hasp and staple hardware found on lockers, gates, and storage units requiring a 40mm body-width lock.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — insert the shackle through the hasp or chain link and close until the locking levers engage. Verify the hasp staple inside diameter is large enough to accept the shackle diameter before installation. For permanent outdoor installations, inspect the shackle and case periodically for corrosion or wear. Do not force a jammed shackle; have a licensed locksmith service the cylinder if the key does not operate smoothly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 40mm (approximately 1.56 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Laminated cadmium rustproof steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShackle Material\u003c\/strong\u003e: Hardened nickel-plated steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCylinder Type\u003c\/strong\u003e: 4-pin pin tumbler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Mechanism\u003c\/strong\u003e: Dual locking levers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKeys Included\u003c\/strong\u003e: 2 brass keys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Height\u003c\/strong\u003e: 5.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Width\u003c\/strong\u003e: 2.75 inches\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 COMPANY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MLK7D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER LOCK","offers":[{"title":"Default Title","offer_id":51723056021810,"sku":"MLK7D","price":22.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0510472871939b95a46364dd40da240.jpg?v=1788599931","url":"https:\/\/voomisupply.com\/products\/master-lock-company-mlk7d-40mm-high-security-padlock","provider":"Voomi Supply","version":"1.0","type":"link"}
