The 2.875-inch-wide metal body houses an internal cavity measuring 4.1875 inches tall by 2.375 inches wide by 1 inch deep, giving it enough room to hold up to 6 keys, key fobs, and access cards. An adjustable vinyl-coated shackle attaches to a wide range of door hardware styles, and a durable weather cover keeps the dial and internals protected from freezing and jamming. Licensed contractors, property managers, and service technicians commonly use this type of box to share access across job sites or rental properties.\u003c\/p\u003e\u003cp\u003eThis lock box suits residential and light commercial applications where temporary or shared key access is required. The user-settable combination dial offers thousands of unique code options, eliminating the need for a manufacturer-assigned code. The adjustable shackle accommodates lever-style, ball, biscuit, and tulip door hardware configurations, making it adaptable across a broad range of residential entry door types. The large internal compartment also accepts bulkier access credentials such as fobs and proximity cards, which is practical for multi-tenant or multi-entry service scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.875-inch-wide durable metal body construction\u003c\/li\u003e\n\u003cli\u003eInternal capacity: 4.1875 inches H x 2.375 inches W x 1 inch D — holds up to 6 keys plus fobs and access cards\u003c\/li\u003e\n\u003cli\u003eUser-settable combination with thousands of unique code options\u003c\/li\u003e\n\u003cli\u003eAdjustable vinyl-coated shackle fits lever, ball, biscuit, and tulip door hardware styles\u003c\/li\u003e\n\u003cli\u003eDurable weather cover resists freezing and jamming in outdoor conditions\u003c\/li\u003e\n\u003cli\u003eMolded bumper and vinyl shackle coating prevent scratches to door finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a portable, hardware-mounted lock box compatible with lever, ball, biscuit, and tulip door hardware styles on most standard residential entry doors.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo tools are required to mount this lock box — the adjustable shackle loops directly around door hardware and cinches in place. Set the combination before deploying the box in the field. Position the weather cover so it fully seats over the dial to maintain weather resistance. Remove the box from service and inspect for corrosion or mechanical wear periodically when used in prolonged outdoor environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Dimensions\u003c\/strong\u003e: 4.1875 inches H x 2.375 inches W x 1 inch D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Capacity\u003c\/strong\u003e: Up to 6 keys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.33 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4\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 CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5420D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER LOCK","offers":[{"title":"Default Title","offer_id":51523474325810,"sku":"5420D","price":290.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76cb3b67b148831856acdbbe75d345e5.jpg?v=1785442364","url":"https:\/\/voomisupply.com\/products\/master-lock-co-5420d-universal-portable-lock-box","provider":"Voomi Supply","version":"1.0","type":"link"}
