It measures 8 inches in diameter with a 2-inch standoff, allowing the fitting to clear insulation or other obstructions on the duct surface. The built-in damper gives installers direct airflow control at the branch point without the need for a separate damper assembly. HVAC technicians and sheet metal contractors install this fitting during new construction or retrofit applications where branch takeoffs are needed from flat trunk duct runs.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is suited for residential and light commercial forced-air distribution systems that use flat duct as the main trunk. The stick-on design speeds installation by bonding directly to the duct surface, eliminating the need to cut and collar the trunk in a traditional manner. The airtight construction helps maintain system efficiency by minimizing conditioned air leakage at the branch connection. It is appropriate for supply-side duct systems where controlled branch airflow and low leakage are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAirtight construction minimizes conditioned air leakage at the branch takeoff point\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper provides airflow control at the branch without a separate assembly\u003c\/li\u003e\n  \u003cli\u003eStick-on installation bonds directly to flat duct surface for faster field installation\u003c\/li\u003e\n  \u003cli\u003e2-inch standoff accommodates duct insulation or surface clearance requirements\u003c\/li\u003e\n  \u003cli\u003e8-inch diameter fits standard round branch duct connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style stick-on takeoff for flat trunk duct systems in residential and light commercial forced-air HVAC installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling unit and confirm the system is de-pressurized before cutting into or modifying any duct section. The stick-on surface must be clean, dry, and free of dust or grease for the adhesive bond to seat properly. Follow local mechanical codes and ACCA Manual D guidelines for branch takeoff sizing and placement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandoff Height\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Type\u003c\/strong\u003e: Flat Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper\u003c\/strong\u003e: Integrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\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: 840-1-ATD200-000008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346757255474,"sku":"840-1-ATD200-000008","price":31.62,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553233.jpg?v=1782089428","url":"https:\/\/voomisupply.com\/products\/air-flow-products-840-1-atd200-000008-stick-on-takeoff-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
