It is commonly used in residential dryer exhaust and HVAC ducting systems where a change in duct geometry is required. The all-aluminum construction keeps the fitting lightweight at 0.9 pounds while providing resistance to corrosion. HVAC technicians and sheet metal installers use this fitting to adapt round flex or rigid duct runs to rectangular boot openings or equipment collars in tight installations.\u003c\/p\u003e\u003cp\u003eThis transition fitting is suited for residential duct systems that require a geometry change between round supply or exhaust duct and standard 3-1\/4 inch x 10 inch rectangular duct. Typical applications include dryer venting transitions and low-profile HVAC supply runs in floor or wall cavities where rectangular duct dimensions are constrained. The fitting ships individually boxed, making it easy to handle as a single-unit replacement or new-install component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConnects 7 inch round duct to 3-1\/4 inch x 10 inch rectangular duct in a single fitting\u003c\/li\u003e\n\u003cli\u003eAluminum construction offers corrosion resistance and low weight\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.9 pounds for easy single-tech handling\u003c\/li\u003e\n\u003cli\u003eIndividually boxed for clean jobsite delivery and storage\u003c\/li\u003e\n\u003cli\u003eSold as a single unit (EA)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install transition fitting for residential HVAC and dryer exhaust duct systems using 7 inch round duct and standard 3-1\/4 inch x 10 inch rectangular duct configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified sheet metal installer. Shut down the air handling system and disconnect power before beginning any ductwork modification. Secure all duct connections with approved foil tape or sheet metal screws per local mechanical codes and SMACNA guidelines. Do not use standard cloth-backed duct tape on dryer exhaust applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRound Duct Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRectangular Duct Size\u003c\/strong\u003e: 3-1\/4 inches x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LAMBRO INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 123IND\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51524701225266,"sku":"123IND","price":27.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/052c00e7c7657a5d25bf91ed983a5ff8.jpg?v=1785455742","url":"https:\/\/voomisupply.com\/products\/lambro-industries-123ind-7-inch-round-aluminum-transition-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
