The body is constructed from layered brass plates, measuring 1-3\/4 inches wide, which provides strength and weather resistance suited for outdoor, marine, and offshore environments. A 4-pin W1 cylinder resists picking and delivers long-term reliability. The hardened steel shackle, measuring 5\/16 inch in diameter and 15\/16 inch in length, is secured by a dual ball bearing locking mechanism that resists cutting, sawing, and prying. Facility managers, security personnel, and maintenance professionals install this lock where dependable keyed-alike access control is needed.\u003c\/p\u003e\u003cp\u003eThis padlock is well suited for gates, tool cribs, equipment storage, and other access points in commercial facilities, marine operations, and outdoor industrial settings. The keyed-alike configuration allows multiple locks to be operated with a single key, reducing the number of keys a technician or facility supervisor must carry. Its laminated brass body performs reliably in humid, salt-air, and wet environments where standard steel locks would corrode prematurely. The dual ball bearing shackle retention adds an additional layer of tamper resistance in high-traffic or unmonitored areas.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLaminated brass body measuring 1-3\/4 inches wide for superior corrosion resistance in marine and outdoor environments\u003c\/li\u003e\n\u003cli\u003eHardened steel shackle with dual ball bearing locking mechanism resists cutting, sawing, and prying\u003c\/li\u003e\n\u003cli\u003e4-pin W1 cylinder provides pick resistance and long-term cylinder reliability\u003c\/li\u003e\n\u003cli\u003eKeyed-alike configuration allows multiple units to operate with the same key for simplified access management\u003c\/li\u003e\n\u003cli\u003eShackle diameter of 5\/16 inch and shackle length of 15\/16 inch suit standard hasp and chain applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style keyed-alike padlock for use in commercial facility, marine, and industrial security applications where a laminated brass body and W1 keyway cylinder are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this padlock requires no tools beyond the hasp, chain, or fitting it secures. Before replacing an existing lock on an energized enclosure or electrical panel, de-energize the circuit and follow applicable NFPA 70E lockout\/tagout procedures. Ensure the shackle clearance of the intended hasp or chain link matches the 5\/16-inch shackle diameter before installation. Inspect the shackle and cylinder periodically in harsh environments and apply a light lubricant to the keyway to maintain smooth operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Laminated Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Diameter\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Length\u003c\/strong\u003e: 15\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Type\u003c\/strong\u003e: 4-Pin W1 Tumbler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Mechanism\u003c\/strong\u003e: Dual Ball Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeying\u003c\/strong\u003e: Keyed Alike\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: 2ka-3553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER LOCK","offers":[{"title":"Default Title","offer_id":51525423169842,"sku":"2KA-3553","price":128.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27358fca78b8f36748060d354605895d.webp?v=1785473364","url":"https:\/\/voomisupply.com\/products\/master-lock-2ka-3553-laminated-brass-padlock-keyed-alike","provider":"Voomi Supply","version":"1.0","type":"link"}
