It connects a main trunk duct to a branch run, redirecting conditioned airflow from the supply plenum or trunk line into a lateral duct. This type of fitting is a standard component in sheet metal duct fabrication and is installed by HVAC technicians during new construction or system retrofit work. The 1203-3010 measures 30 inches by 10 inches, making it suited for medium-to-large capacity residential or light commercial duct systems where a properly sized branch connection is critical to maintaining system static pressure and airflow balance.\u003c\/p\u003e\u003cp\u003eTransition take offs like the 1203-3010 are used in forced-air heating and cooling systems where trunk-and-branch duct layouts are employed. The fitting transitions between the main duct trunk and a smaller branch duct run, allowing installers to tap off airflow at a designated point along the duct system. This fitting is appropriate for residential applications and light commercial builds where sheet metal ductwork is the specified distribution method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-inch by 10-inch throat dimensions for medium-to-large branch connections\u003c\/li\u003e\n\u003cli\u003eDesigned for trunk-to-branch duct transitions in forced-air HVAC systems\u003c\/li\u003e\n\u003cli\u003eCompatible with standard sheet metal duct fabrication and installation methods\u003c\/li\u003e\n\u003cli\u003eSupports proper airflow distribution and static pressure balance across branch runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use in residential and light commercial forced-air duct systems utilizing trunk-and-branch supply configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with sheet metal ductwork and local mechanical codes. Shut down the air handling unit and confirm the system is de-energized before cutting into any existing duct trunk. Secure the fitting to the trunk with sheet metal screws and seal all joints with listed duct sealant or UL-listed tape per applicable mechanical code requirements. Support the branch duct run independently to prevent stress on the take off connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 30 inches x 10 inches\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SEAL-TITE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1203-3010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51342782759218,"sku":"1203-3010","price":244.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553459.jpg?v=1782006461","url":"https:\/\/voomisupply.com\/products\/seal-tite-1203-3010-transition-take-off-30x10-in","provider":"Voomi Supply","version":"1.0","type":"link"}
