The locknut threads onto the male threads of a conduit fitting and is tightened against the enclosure wall to create a rigid, low-resistance mechanical connection. It is a standard consumable in electrical rough-in work and is installed by licensed electricians on both commercial and residential projects. The steel construction provides the mechanical strength needed to maintain a solid, code-compliant grounding path through metallic conduit systems.\u003c\/p\u003e\n\u003cp\u003eThe ARLINGTON 408 is used wherever 3-inch conduit terminates at an enclosure — including panelboards, wireways, junction boxes, and pull boxes. It is suited for rigid metal conduit (RMC), intermediate metal conduit (IMC), and compatible threaded fittings at the 3-inch trade size. This fitting is a staple of high-ampacity feeder runs and large service entrance installations where 3-inch conduit is common.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch trade size fits standard 3-inch conduit connector threads\u003c\/li\u003e\n  \u003cli\u003eSteel construction delivers mechanical strength and a reliable grounding continuity path\u003c\/li\u003e\n  \u003cli\u003eThreaded design allows hand-start installation with wrench or locknut wrench tightening\u003c\/li\u003e\n  \u003cli\u003eCompact profile seats flush against enclosure walls for clean terminations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.162 pounds, minimizing added load at enclosure knockouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use locknut for 3-inch trade size metallic conduit fittings in commercial and residential electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstalled by licensed electricians in accordance with NEC requirements for securing conduit fittings to enclosures. De-energize the panel or enclosure before working at any knockout entry point. Thread the locknut onto the fitting by hand, then tighten firmly with a locknut wrench or flathead screwdriver and hammer to ensure solid metal-to-metal contact for grounding continuity. Do not overtighten to the point of deforming the enclosure wall.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.162 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 01899700408\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ARLINGTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARLINGTON","offers":[{"title":"Default Title","offer_id":51383466656050,"sku":"408","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677097.jpg?v=1782597475","url":"https:\/\/voomisupply.com\/products\/arlington-408-steel-locknut-3-inch-conduit","provider":"Voomi Supply","version":"1.0","type":"link"}
