This fitting connects two sections of rigid metal conduit (RMC) or intermediate metal conduit (IMC) where standard one-piece couplings cannot be installed due to limited access or fixed conduit positions. The three-piece design allows the coupling to be assembled around stationary conduit without rotating either conduit section. Licensed electricians and electrical contractors install this type of fitting in industrial, commercial, and heavy-duty residential conduit systems that require a secure, code-compliant mechanical connection.\u003c\/p\u003e\n\u003cp\u003eThe 4-350 is suited for 3.5-inch rigid or intermediate metal conduit installations in applications where conduit cannot be turned, such as long straight runs, conduit already anchored to structure, or retrofit work on existing raceways. Common install environments include industrial plants, commercial buildings, utility infrastructure, and similar settings where malleable iron fittings are specified for mechanical durability and resistance to physical damage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-piece construction allows installation on fixed conduit without rotating either section\u003c\/li\u003e\n  \u003cli\u003eMalleable iron body provides high mechanical strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003eSized for 3.5-inch trade-size conduit (RMC or IMC)\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at approximately 6.9 x 5.3 x 4.1 inches overall package dimensions\u003c\/li\u003e\n  \u003cli\u003eWeighs 5.5 pounds, consistent with heavy-duty malleable iron construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 3.5-inch trade-size rigid metal conduit or intermediate metal conduit 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 all circuits in the conduit run before beginning work. Ensure conduit threads are clean and free of burrs before assembly; apply listed thread compound or tape as required by the authority having jurisdiction. Tighten all three coupling sections evenly to achieve a secure, continuous metallic raceway bond.\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\u003ePieces\u003c\/strong\u003e: 3-piece assembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 6.9 x 5.3 x 4.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78312661285\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: APPLETON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4-350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APPLETON","offers":[{"title":"Default Title","offer_id":51383705600306,"sku":"4-350","price":529.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676325.jpg?v=1782604959","url":"https:\/\/voomisupply.com\/products\/appleton-4-350-malleable-iron-3-piece-conduit-coupling-3-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
