This fitting threads onto the end of rigid metal conduit or intermediate metal conduit to provide a smooth, insulated throat that protects conductor insulation from abrasion at entry points. It also provides a grounding lug or bonding connection point, making it a code-required component in many service entrance and feeder conduit terminations. Electricians rely on this bushing to meet NEC bonding requirements at enclosure knockouts where conduit terminates.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for commercial and industrial electrical installations where 3.5-inch rigid or IMC conduit terminates at panelboards, switchgear, junction boxes, and service entrance enclosures. It is a standard component in new construction wiring, service upgrades, and conduit retrofit work requiring proper bonding continuity at conduit terminations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.5-inch trade size fits standard rigid metal conduit and IMC terminations\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction for durability in demanding installation environments\u003c\/li\u003e\n  \u003cli\u003eInsulated throat protects conductor insulation from conduit edge damage\u003c\/li\u003e\n  \u003cli\u003eGrounding and bonding connection point supports NEC compliance at conduit terminations\u003c\/li\u003e\n  \u003cli\u003eThreaded design for secure, tool-tightened connection to conduit end threads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for 3.5-inch rigid metal conduit and intermediate metal conduit terminations in commercial and industrial electrical systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit or service before working at any enclosure or panelboard where this bushing will be installed. Thread the bushing securely onto the conduit end using appropriate conduit wrenches, then connect the bonding jumper or grounding conductor to the lug as required. Do not overtighten in a way that cracks the insulated throat.\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: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75133813430\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: 339M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51383995990322,"sku":"339M","price":20.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675362.jpg?v=1782614529","url":"https:\/\/voomisupply.com\/products\/southwire-339m-insulated-grounding-bushing-3-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
