This type of fitting creates a firm mechanical connection between rigid or IMC conduit and the entry knockout of an electrical enclosure. It is used in commercial and industrial electrical installations where a code-compliant, secure conduit termination is required. Licensed electricians install this fitting during rough-in and panel work, relying on the compression design to maintain a tight, rattle-free connection that meets wiring method requirements.\u003c\/p\u003e\n\u003cp\u003eThe NSI INDUSTRIES 259 is suited for use in commercial construction, industrial facilities, and large residential service work where 4-inch conduit runs terminate at enclosures or distribution equipment. The compression-style design is a common requirement in installations governed by the National Electrical Code, particularly where secure mechanical attachment and continuous ground path integrity are priorities. This connector is installed by licensed electricians and electrical contractors working on conduit systems requiring robust, durable fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch trade size fits standard 4-inch rigid or IMC conduit knockouts\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability and mechanical strength at conduit termination points\u003c\/li\u003e\n  \u003cli\u003eCompression-style design delivers a secure, tight fit without loosening over time\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard knockout openings on enclosures, panels, and junction boxes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use compression connector for 4-inch conduit terminations at electrical enclosures and panels.\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 and lock out the panel or enclosure before beginning work. Use appropriate conduit wrenches or pliers to tighten the compression nut to a firm, secure fit without over-tightening, which could damage the fitting or conduit. Verify the connection maintains continuity for the equipment grounding conductor path before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78174700259\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: NSI INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NSI INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383209230642,"sku":"259","price":146.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678590.jpg?v=1782589736","url":"https:\/\/voomisupply.com\/products\/nsi-industries-259-steel-compression-connector-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
