It provides a sealed branch connection point on round ductwork without requiring sheet metal cutting tools or crimping equipment at the takeoff location. The self-adhesive mounting design allows the fitting to bond directly to the duct surface, forming an airtight seal that reduces conditioned air leakage at branch connections. HVAC installers and sheet metal mechanics use this fitting during new duct installations and duct modification work on forced-air systems.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial forced-air HVAC ductwork where round branch takeoffs are required. It is commonly installed on main trunk lines or large-diameter round runs to serve individual supply branches. The 4-inch round opening matches standard 4-inch round duct and flex duct connections used throughout residential supply distribution systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAirtight adhesive mounting eliminates the need for additional sealant at the takeoff face\u003c\/li\u003e\n  \u003cli\u003eStick-on installation reduces labor time compared to traditional cut-in collar methods\u003c\/li\u003e\n  \u003cli\u003e4-inch round outlet connects directly to standard 4-inch round duct or flex duct\u003c\/li\u003e\n  \u003cli\u003eRound profile fits standard round pipe without adapters\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 standard round forced-air supply ductwork systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handler and ensure the system is depressurized before cutting into any duct section or attaching the fitting. Clean and dry the duct surface thoroughly before applying the adhesive backing to ensure a proper airtight seal. Follow local mechanical codes and SMACNA duct construction standards for branch takeoff placement and spacing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Stick-On Adhesive\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: 84RAT04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346249679154,"sku":"84RAT04","price":29.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553247.jpg?v=1782075157","url":"https:\/\/voomisupply.com\/products\/air-flow-products-84rat04-stick-on-takeoff-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
