The body is constructed from die cast metal with a solid brass case for strength and weather resistance, finished in black. The 4-digit combination can be reset on-site using the included change key, eliminating the need to replace the lock when access credentials change. A 1-inch hardened steel shackle with a 5\/16-inch diameter provides cut resistance. At 2.24 pounds per unit, this padlock is a substantial, commercial-grade option suited to gate, locker, and equipment enclosure applications.\u003c\/p\u003e\u003cp\u003eThe 178D is appropriate for both residential and light commercial use anywhere a resettable combination lock is specified. Typical installations include storage units, utility enclosures, gates, and job site equipment boxes where keyless access is preferred and multiple authorized users may require combination changes over time. Packaged individually (sold as EA), with a package quantity of 4 per carton, making it practical for multi-unit procurement on service accounts or facilities contracts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid brass case construction for strength and weatherability\u003c\/li\u003e\n\u003cli\u003eDie cast body with black finish\u003c\/li\u003e\n\u003cli\u003e4-digit resettable combination — no locksmith required\u003c\/li\u003e\n\u003cli\u003eChange key included for on-site combination reset\u003c\/li\u003e\n\u003cli\u003e1-inch hardened steel shackle with 5\/16-inch shackle diameter\u003c\/li\u003e\n\u003cli\u003eKeyless operation suits shared-access and facilities applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standalone resettable combination padlock suitable for standard hasp, locker, gate latch, and equipment enclosure applications where a 2-inch padlock body is appropriate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no specialized tools — the shackle is inserted into the hasp or locking point and closed by hand. Before resetting the combination, confirm the existing combination is known and follow the change key procedure to avoid locking out the mechanism. Inspect the shackle clearance on the hasp or locking bar before purchase to confirm the 5\/16-inch shackle diameter and 1-inch shackle length are compatible with the hardware being secured. When used on exterior or exposed applications, orient the shackle opening downward where possible to reduce moisture intrusion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Width\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Solid Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Construction\u003c\/strong\u003e: Die Cast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShackle Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCombination Digits\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChange Key\u003c\/strong\u003e: Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.24 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: MASTER LOCK CO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 178D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER LOCK","offers":[{"title":"Default Title","offer_id":51525504303410,"sku":"178D","price":77.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1c79f873481b96b4623f95042ab0b98.jpg?v=1785475818","url":"https:\/\/voomisupply.com\/products\/master-lock-co-178d-resettable-combination-padlock","provider":"Voomi Supply","version":"1.0","type":"link"}
