This ring provides a 3-1\/2-inch depth to accommodate wiring connections and device mounting in concrete ceiling applications. It is installed by licensed electricians during the rough-in phase of commercial and residential construction, typically before concrete is poured. The ring establishes the correct setback for the outlet box so that box faces align flush with the finished ceiling surface after the pour.\u003c\/p\u003e\n\u003cp\u003eThis concrete ring is suited for poured-concrete ceiling and slab installations in residential and light commercial construction. It is used in conjunction with standard 4-inch octagonal outlet boxes and is positioned on formwork prior to the concrete pour. The 3-1\/2-inch depth makes it appropriate for thicker slab applications where standard extension rings would not provide adequate depth. Electricians working on multi-family, commercial, or concrete-framed residential projects will find this a standard rough-in component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch octagonal form factor compatible with standard octagonal outlet box installations\u003c\/li\u003e\n  \u003cli\u003e3-1\/2-inch depth provides extended setback for thick concrete slab applications\u003c\/li\u003e\n  \u003cli\u003eDesigned for poured-concrete ceiling rough-in work\u003c\/li\u003e\n  \u003cli\u003eSold in carton quantities of 20 units for jobsite efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard rough-in component for use with 4-inch octagonal electrical outlet boxes in poured-concrete ceiling and slab construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician during the concrete forming stage, prior to the pour. Secure the ring to the formwork so it remains stationary when concrete is placed. Verify box depth and setback requirements comply with local codes and NEC guidelines before the pour. Do not reposition or adjust the ring after concrete has cured.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Shape\u003c\/strong\u003e: Octagonal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarton Quantity\u003c\/strong\u003e: 20 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarton Weight\u003c\/strong\u003e: 18.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarton Dimensions (L x W x H)\u003c\/strong\u003e: 20.88 inches x 9 inches x 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 05016900278\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: RACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RACO","offers":[{"title":"Default Title","offer_id":51383766155570,"sku":"278","price":70.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677103.jpg?v=1782606785","url":"https:\/\/voomisupply.com\/products\/raco-278-4-in-octagon-3-1-2-in-deep-concrete-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
