It provides a secure, non-insulated metal-to-metal connection between two sections of EMT conduit at a 2-1\/2 inch trade size. Constructed from die cast zinc, it is rated for concrete-tight applications, making it suitable for installations where the raceway will be embedded or in contact with concrete. Licensed electricians and electrical contractors install this fitting as part of branch circuit and feeder conduit runs in both commercial and residential electrical systems.\u003c\/p\u003e\u003cp\u003eThis coupling is used in EMT conduit systems where a mechanical set-screw connection is required at 2-1\/2 inch trade size. Its concrete-tight rating makes it appropriate for slab, pour-in-place, and masonry applications where conduit joints must resist moisture infiltration during and after concrete placement. It is a standard choice for junction and transition points along horizontal and vertical EMT runs in commercial construction, industrial facilities, and residential service installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSet-screw connection type for positive mechanical engagement without threading\u003c\/li\u003e\n\u003cli\u003eDie cast zinc construction provides corrosion resistance and structural integrity\u003c\/li\u003e\n\u003cli\u003eConcrete-tight rated for embedded or masonry conduit installations\u003c\/li\u003e\n\u003cli\u003eNon-insulated design for standard EMT metallic raceway continuity\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch trade size fits standard 2-1\/2 inch EMT conduit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 2-1\/2 inch trade size EMT conduit in concrete-tight set-screw coupling applications.\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 conduit run before making any connections or modifications. Tighten set screws to manufacturer specification using an appropriate hex key or screwdriver to ensure a secure, code-compliant mechanical connection. Verify that the conduit ends are clean, burr-free, and fully seated before securing the coupling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Conduit Type\u003c\/strong\u003e: EMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Set Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Die Cast Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation\u003c\/strong\u003e: Non-Insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArea of Application\u003c\/strong\u003e: Concrete Tight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 89.58 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: THOMAS BETTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TK227SC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51539403374898,"sku":"TK227SC","price":59.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/264d9efcd142dbd503483cf66c992717.jpg?v=1785839332","url":"https:\/\/voomisupply.com\/products\/thomas-betts-tk227sc-emt-conduit-coupling-2-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
