It joins two sections of EMT conduit with a secure set screw connection, maintaining electrical continuity through the raceway system. Constructed from die cast zinc, this coupling is rated for concrete tight applications, making it suitable for installations where the fitting may be encased or embedded. Licensed electricians and electrical contractors install this type of fitting during rough-in wiring on commercial and residential projects. The 1-1\/4 inch trade size suits medium-diameter EMT runs commonly found in branch circuit and feeder installations.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in EMT conduit systems in both residential and commercial electrical installations. It is well suited for exposed conduit runs, embedded slab work, and other applications requiring a concrete tight fitting. The set screw design allows for fast field installation without special tooling beyond a standard screwdriver or hex key. It is sold as a single unit and is appropriate wherever a 1-1\/4 inch EMT coupling is called for on the job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSet screw connection type for secure, tool-friendly assembly\u003c\/li\u003e\n  \u003cli\u003eDie cast zinc construction for durability in standard wiring environments\u003c\/li\u003e\n  \u003cli\u003eConcrete tight rating suitable for embedded or encased installations\u003c\/li\u003e\n  \u003cli\u003eNon-insulated design for standard EMT coupling applications\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch trade size fits commonly specified medium conduit runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard coupling for 1-1\/4 inch EMT conduit systems in residential and commercial electrical installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the affected raceway before beginning conduit work. Ensure conduit ends are reamed and free of burrs before inserting into the coupling to prevent conductor insulation damage. Tighten set screws to the fitting manufacturer's recommended engagement using an appropriate screwdriver or hex key.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1-1\/4 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: 28.3 pounds\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: THOMAS BETTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TK224SC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51544497160498,"sku":"TK224SC","price":18.32,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d597ab26cc8d8dafd71b5e337ba1859.jpg?v=1785928131","url":"https:\/\/voomisupply.com\/products\/thomas-betts-tk224sc-emt-conduit-coupling-1-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
