Constructed from zinc electroplated malleable iron, it provides a smooth, non-insulated throat surface that protects cable insulation during pull-through. The bushing is installed in conjunction with a locknut to secure the conduit termination and maintain a clean, code-compliant connection point. Licensed electricians and commercial-industrial wiremen install this fitting as a standard termination component in conduit raceway systems.\u003c\/p\u003e\n\u003cp\u003eThe BU-350 is suited for commercial and industrial applications where 3-1\/2 inch rigid metal conduit or IMC enters an enclosure, panelboard, junction box, or other electrical housing. Its non-insulated throat is appropriate for installations where a separate grounding bushing or locknut provides the required ground continuity. The fitting measures 4.44 inches in diameter and 0.94 inches in height, and conforms to NEMA FB-1 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThreaded female design secures onto male-threaded rigid conduit or IMC ends\u003c\/li\u003e\n  \u003cli\u003eZinc electroplated malleable iron construction for corrosion resistance and mechanical strength\u003c\/li\u003e\n  \u003cli\u003eNon-insulated smooth throat protects cable insulation during wire pulling\u003c\/li\u003e\n  \u003cli\u003eConforms to NEMA FB-1 standard for conduit fittings\u003c\/li\u003e\n  \u003cli\u003eUL 514B listed and CSA C22.2 certified for use in commercial and industrial installations\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch trade size fits standard rigid conduit and IMC of matching thread size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3-1\/2 inch trade size rigid metal conduit and IMC.

De-energize and lock out the circuit before working inside any enclosure. Thread the bushing onto the conduit end and tighten with a strap wrench or suitable conduit tool, then secure with a locknut on the inside of the enclosure. Do not substitute this non-insulated bushing where a grounding or insulated throat bushing is required by code.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Threaded Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Type\u003c\/strong\u003e: Non-Insulated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc Electroplated Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Rigid Conduit \/ IMC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial \/ Industrial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.800 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL 514B, CSA C22.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: NEMA FB-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: MX\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: BU-350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APPLETON","offers":[{"title":"Default Title","offer_id":51283907182898,"sku":"BU-350","price":37.27,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279633.jpg?v=1781062949","url":"https:\/\/voomisupply.com\/products\/appleton-bu-350-conduit-bushing-3-1-2-in-threaded-female","provider":"Voomi Supply","version":"1.0","type":"link"}
