This fitting connects two sections of EMT conduit end-to-end, securing the joint with set screws for a reliable mechanical connection. Aluminum construction keeps weight low while providing corrosion resistance suitable for a range of installation environments. Licensed electricians install this type of fitting during rough-in and finish wiring stages on both new construction and retrofit projects. At 8 pounds, this package is sized for job-site use by electrical contractors working with larger conduit runs.\u003c\/p\u003e\u003cp\u003eThe ELR10 is suited for 4-inch EMT conduit installations in commercial and industrial electrical work. Typical applications include branch circuit wiring, feeder runs, and equipment connection in panel rooms, mechanical spaces, and exposed conduit systems. The set-screw design allows for straightforward field installation without specialized crimping tools, making it a practical choice for high-volume conduit runs where speed and repeatability matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch trade size for use with 4-inch EMT conduit\u003c\/li\u003e\n\u003cli\u003eAluminum construction for lightweight handling and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSet-screw securing method for positive mechanical connection\u003c\/li\u003e\n\u003cli\u003eConnects two EMT conduit sections in a straight-line coupling configuration\u003c\/li\u003e\n\u003cli\u003eSuitable for commercial and industrial conduit installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for 4-inch EMT conduit systems in commercial and industrial electrical installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\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 work area before assembling or modifying conduit runs. Tighten set screws using the appropriate hex key or driver to achieve a secure mechanical connection without stripping the screw heads. Inspect conduit ends for burrs or deformation before coupling to ensure proper seating and electrical continuity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Set-screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConduit Type\u003c\/strong\u003e: EMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ELR10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51383032611122,"sku":"ELR10","price":103.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675239.jpg?v=1782586142","url":"https:\/\/voomisupply.com\/products\/southwire-elr10-4-in-aluminum-set-screw-emt-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
