Measuring 3.5 inches in diameter and 1.5 inches in depth, it provides 11.8 cubic inches of additional wiring space. The ring is fabricated from 0.0625-inch pre-galvanized sheet steel and includes four 0.5-inch knockouts on the conduit sides. Licensed electricians install this component during rough-in and finish electrical work where box fill calculations require added capacity under NEC Article 314.\u003c\/p\u003e\n\u003cp\u003eThe RACO 111 extension ring is used in residential and light commercial electrical installations wherever an existing 3.5-inch octagon box does not provide sufficient cubic capacity for the number of conductors, devices, or fittings present. It is also used as a standalone outlet box for surface-mounted conduit runs. Combination screw heads on the ring allow faster installation with either a flathead or Phillips driver, reducing time on multi-box jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdds 11.8 cubic inches of capacity to an existing octagon box installation\u003c\/li\u003e\n  \u003cli\u003eFour 0.5-inch conduit-side knockouts for flexible conduit entry routing\u003c\/li\u003e\n  \u003cli\u003eDrawn construction from 0.0625-inch pre-galvanized sheet steel for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eCombination screw heads accept both flathead and Phillips drivers for faster installation\u003c\/li\u003e\n  \u003cli\u003eListed to UL 514A and CSA C22.2; compliant with ANSI and NEMA OS1 standards\u003c\/li\u003e\n  \u003cli\u003eFunctions as a surface conduit outlet box when used independently\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and add-on extension for standard 3.5-inch octagon electrical outlet boxes in residential and light commercial wiring systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with NEC Article 314 and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage before opening any box. Secure the extension ring flush to the existing box using the provided combination-head screws, and ensure all knockout openings not in use are properly closed with listed fillers. Box fill calculations must account for all conductors, fittings, and devices within the combined volume after the extension ring is added.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Octagon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 11.8 cubic inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Knockouts\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnockout Size\u003c\/strong\u003e: 0.5 inches (conduit sides)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 0.0625-inch pre-galvanized sheet steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction Type\u003c\/strong\u003e: Drawn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL 514A, CSA C22.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ANSI, NEMA OS1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25 per carton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 8.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico\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: 111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RACO","offers":[{"title":"Default Title","offer_id":51284156940594,"sku":"111","price":3181.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279109.jpg?v=1781070032","url":"https:\/\/voomisupply.com\/products\/raco-111-octagon-extension-ring-3-5-in-pre-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
