It provides a secure, sealed branch connection point directly on flat duct without requiring cutting or sheet metal fabrication beyond the takeoff opening. The adhesive-backed design speeds up installation and reduces air leakage at the branch point, making it a practical choice for residential and light commercial HVAC duct distribution work. At 18 inches, it suits a range of branch duct runs where a clean, low-leakage connection is required.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is used in forced-air HVAC systems where flat duct serves as the main trunk or branch distribution pathway. It is suited for residential new construction and retrofit applications where maintaining duct airtightness is a priority. HVAC installers and sheet metal mechanics use this fitting when branch taps need to be added to flat duct runs without compromising the integrity of the duct system. The stick-on installation method makes it well-suited for tight ceiling or crawlspace installations where access is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAirtight construction minimizes air leakage at branch takeoff points\u003c\/li\u003e\n  \u003cli\u003eStick-on adhesive backing eliminates the need for separate fasteners at the seal point\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for flat duct applications\u003c\/li\u003e\n  \u003cli\u003e18-inch size accommodates a range of branch duct run requirements\u003c\/li\u003e\n  \u003cli\u003eSimplifies branch connections in new construction and retrofit duct work\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 flat duct HVAC distribution systems requiring airtight branch takeoff connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal mechanics. The duct system should be depressurized and the air handler powered down before cutting into any existing duct run. Ensure the flat duct surface is clean and free of dust or grease before applying the adhesive-backed fitting to achieve a proper airtight seal. Local mechanical codes and ASHRAE duct leakage standards may apply to the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Type\u003c\/strong\u003e: Flat Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Style\u003c\/strong\u003e: Stick-On Takeoff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Airtight\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: AIR FLOW PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84AT18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51344748871986,"sku":"84AT18","price":45.79,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554436.jpg?v=1782042517","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84at18-stick-on-takeoff-flat-duct-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
