It features a 7-inch collar and a 2-inch standoff profile, making it suitable for low-clearance installations where standard takeoff fittings will not fit. The built-in damper allows for airflow adjustment at the branch point without the need for a separate damper component. Licensed HVAC technicians and sheet metal installers are the primary tradespeople who work with this fitting during duct fabrication or retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is intended for residential and light commercial duct systems that use flat or low-profile ductwork configurations. The stick-on design allows it to be secured directly to the flat duct surface, simplifying installation in tight spaces such as floor cavities, dropped ceilings, or between-joist runs where conventional round or rectangular collars are impractical. The integrated damper provides branch-level balancing capability at the point of takeoff.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAirtight construction minimizes conditioned-air leakage at the branch connection\u003c\/li\u003e\n  \u003cli\u003eStick-on mounting attaches directly to flat duct surface without additional framing\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper allows airflow adjustment at the takeoff point\u003c\/li\u003e\n  \u003cli\u003e7-inch collar size suits common branch duct diameters\u003c\/li\u003e\n  \u003cli\u003e2-inch standoff profile supports low-clearance installation environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for flat duct systems requiring an airtight stick-on takeoff with damper functionality.\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 worker. Shut down the air handling unit and confirm the system is depressurized before cutting into the duct or applying the fitting. Follow local mechanical codes and SMACNA duct construction standards for sealing and support requirements. Do not operate the damper adjustment without verifying the fitting is fully adhered and sealed to the duct surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Size\u003c\/strong\u003e: 7 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\u003eMounting Style\u003c\/strong\u003e: Stick-On\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-ATD200-000007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346772558130,"sku":"840-1-ATD200-000007","price":29.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553248.jpg?v=1782089879","url":"https:\/\/voomisupply.com\/products\/air-flow-products-840-1-atd200-000007-stick-on-takeoff-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
