Bonding locknuts differ from standard locknuts by providing a low-impedance ground path required by NEC installations where standard locknuts alone do not satisfy bonding requirements. This fitting is installed by licensed electricians during conduit termination work on service entrances, subpanels, and equipment enclosures in both residential and commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe LNS350G is suited for conduit termination points where the NEC requires positive bonding continuity, particularly at service equipment and in installations involving metal conduit systems. Its 3.5-inch trade size makes it appropriate for larger-diameter conduit runs commonly found in commercial, industrial, and heavy residential service work. Electricians specify this type of bonding locknut when standard locknuts are insufficient to meet grounding and bonding requirements under Article 250 of the NEC.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel construction for durability in conduit termination applications\u003c\/li\u003e\n  \u003cli\u003e3.5-inch trade size for use with larger conduit systems\u003c\/li\u003e\n  \u003cli\u003eBonding design provides low-impedance electrical bond at enclosure entry points\u003c\/li\u003e\n  \u003cli\u003eOne Year Limited Warranty from SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003eManufactured in Indonesia\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard bonding locknut for 3.5-inch trade-size metal conduit terminations in NEC-compliant electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician. De-energize the circuit and verify the panel or enclosure is de-energized before beginning conduit termination work. Thread the bonding locknut onto the conduit and tighten securely against the enclosure wall to ensure a positive metal-to-metal bond; use an appropriate conduit wrench or strap wrench for final tightening. Verify installation meets all applicable NEC Article 250 bonding and grounding requirements for the jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3.5 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: 0.543 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: One Year Limited\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Indonesia\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: SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LNS350G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51348030390578,"sku":"LNS350G","price":22.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552423.png?v=1782118607","url":"https:\/\/voomisupply.com\/products\/southwire-lns350g-steel-bonding-locknut-3-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
