This fitting serves as a critical transition point between round flex or rigid duct runs and flat rectangular duct sections, allowing installers to route airflow through tight spaces or into wall cavities. Constructed from aluminum, it offers corrosion resistance and durability suitable for supply and exhaust duct applications. HVAC technicians and sheet metal installers use this fitting during new construction and retrofit projects where duct geometry changes are required.\u003c\/p\u003e\n\u003cp\u003eThis transition fitting is commonly used in forced-air heating and cooling systems where round trunk lines or branch ducts must connect to rectangular boot-style ductwork. It is well suited for residential furnace and air handler installations, kitchen exhaust rough-in, and bathroom or utility ventilation runs that transition between duct shapes. The individually boxed packaging helps protect the fitting during transport and storage on the job site.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions from 6-inch round duct to 3.25-inch by 10-inch rectangular duct in a single fitting\u003c\/li\u003e\n  \u003cli\u003eAluminum construction resists corrosion in supply and exhaust air applications\u003c\/li\u003e\n  \u003cli\u003eCompact design suits installations in wall cavities, floor joist bays, and tight mechanical spaces\u003c\/li\u003e\n  \u003cli\u003eIndividually boxed for job site handling and protection\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for precise quantity ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for HVAC duct systems requiring a transition between 6-inch round ductwork and 3.25-inch by 10-inch rectangular duct sections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with local mechanical codes and SMACNA duct construction standards. Power down and lock out the air handling unit before making connections to any supply or return duct branch. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant to prevent air leakage. Do not exceed the pressure ratings appropriate for residential low-pressure duct systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound Duct Size\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRectangular Duct Size\u003c\/strong\u003e: 3.25 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: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 each\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: LAMBRO INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 122IND\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LAMBRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51525089132850,"sku":"122IND","price":25.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/052c00e7c7657a5d25bf91ed983a5ff8_0e257513-8d79-45e0-a033-63f2a4fab160.jpg?v=1785464031","url":"https:\/\/voomisupply.com\/products\/lambro-industries-122ind-round-aluminum-transition-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
