The body measures 1.75 inches wide and 0.75 inches thick, housing a 5-pin tumbler cylinder on a keyed-different configuration, meaning each lock ships with its own unique key set. The shackle is boron alloy steel, measuring 0.3125 inches in diameter, 0.75 inches of clearance width, and 2 inches in height. At 0.83 pounds, this is a solid, compact lock suited for gate hasps, tool cribs, HVAC equipment lockout points, panel enclosures, and valve lockout applications.\u003c\/p\u003e\u003cp\u003eThe A21 fits residential and light commercial access control needs where a non-rekeyable, keyed-different padlock is acceptable. Common install scenarios include securing electrical panel enclosures per NFPA 70E lockout-tagout procedures, chaining HVAC condenser units, gate access points, and storage areas on service vehicles or job sites. The non-rekeyable design keeps key control straightforward for single-user or single-asset assignments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-pin tumbler cylinder for improved pick resistance over standard 4-pin designs\u003c\/li\u003e\n\u003cli\u003eBoron alloy steel shackle offers greater cut resistance than standard hardened steel\u003c\/li\u003e\n\u003cli\u003eKeyed different — each lock includes its own unique key\u003c\/li\u003e\n\u003cli\u003eRectangular steel body provides a compact, durable profile\u003c\/li\u003e\n\u003cli\u003eNon-rekeyable construction simplifies key control for dedicated-asset use\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.83 pounds for easy carry and repeated daily use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit padlock for standard hasp and shackle-loop applications requiring a 1.75-inch rectangular-body lock with a 0.75-inch shackle clearance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified tradespeople following applicable lockout-tagout procedures per NFPA 70E or OSHA 29 CFR 1910.147 before securing electrical or mechanical equipment. Verify hasp slot width and shackle clearance requirements before selecting this lock for a specific application. Do not force the shackle into an undersized hasp, as this can damage the locking mechanism. Store keys separately from the locked asset to maintain effective access control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Material\u003c\/strong\u003e: Boron Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Clearance Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Height\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Type\u003c\/strong\u003e: Keyed Different\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pins\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRekeyable\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AMERICAN LOCK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AMERICAN LOCK","offers":[{"title":"Default Title","offer_id":51541717352754,"sku":"A21","price":49.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e6f74195067b362020d660741273a03.jpg?v=1785882917","url":"https:\/\/voomisupply.com\/products\/american-lock-a21-steel-padlock-keyed-different-5-pin","provider":"Voomi Supply","version":"1.0","type":"link"}
