The 2-inch wide laminated steel body delivers superior resistance to physical attack, while the 2.5-inch tall, 0.375-inch diameter hardened boron alloy shackle provides strong cut resistance. A dual ball bearing locking mechanism resists prying, and the non-rekeyable 4-pin W1 cylinder is engineered to resist picking. This padlock is ordered as a keyed-alike unit, meaning multiple locks operate with the same key — a practical setup for facilities, job sites, and equipment yards where one key needs to open several locks.\u003c\/p\u003e\u003cp\u003eThis padlock suits industrial, commercial, and trade applications where consistent, reliable access control is required across multiple lock points. Keyed-alike configurations are common in electrical panel rooms, mechanical rooms, storage cages, gate hasps, and equipment lockout-tagout programs. Any facility or service professional managing multiple secured access points benefits from the keyed-alike W1 cylinder arrangement. Additional locks keyed to the W1 cylinder can be ordered to expand coverage across a site without adding keys to a ring.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch wide reinforced laminated steel body for extra structural strength\u003c\/li\u003e\n\u003cli\u003eHardened boron alloy shackle — 2.5 inches tall, 0.375 inches in diameter — for cut resistance\u003c\/li\u003e\n\u003cli\u003eDual ball bearing locking mechanism maximizes pry resistance\u003c\/li\u003e\n\u003cli\u003eNon-rekeyable 4-pin W1 cylinder resists picking attempts\u003c\/li\u003e\n\u003cli\u003eKeyed alike — multiple units open with one key; compatible with other W1 cylinder locks\u003c\/li\u003e\n\u003cli\u003eCommercial-grade construction rated for industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eKeyed alike to the W1 cylinder; additional locks ordered with the W1 cylinder designation will operate on the same key.

For lockout-tagout (LOTO) applications, verify compliance with OSHA 29 CFR 1910.147 before deploying. Inspect the hasp, staple, or latch hardware for adequate clearance to accept the 0.375-inch diameter shackle before purchase. Do not force the shackle; if resistance is felt during operation, inspect the lock body and shackle for debris or damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Laminated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Height\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Material\u003c\/strong\u003e: Hardened Boron Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Mechanism\u003c\/strong\u003e: Dual Ball Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Type\u003c\/strong\u003e: 4-Pin W1, Non-Rekeyable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeying\u003c\/strong\u003e: Keyed Alike\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5KALJ-A445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER LOCK","offers":[{"title":"Default Title","offer_id":51344902979890,"sku":"5KALJ-A445","price":27.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310513592.jpg?v=1782044976","url":"https:\/\/voomisupply.com\/products\/master-lock-5kalj-a445-laminated-steel-padlock-keyed-alike","provider":"Voomi Supply","version":"1.0","type":"link"}
