A stackhead connects a vertical supply duct stack to a floor or sidewall register boot, making it a key transition component in forced-air distribution. This unit features a 9 inch throat dimension and an oval body measuring 6x12-7, allowing it to interface with standard oval duct runs. HVAC installers and sheet metal contractors select this type of fitting when roughing in supply air distribution in new construction or retrofit applications.\u003c\/p\u003e\n\u003cp\u003eThis stackhead is suited for forced-air heating and cooling installations where oval ductwork feeds floor registers or wall boots in residential and light commercial buildings. The 9 inch throat dimension makes it appropriate for supply runs requiring that collar size. It is installed during rough-in before drywall or flooring is set, and it works with standard oval duct sizes common in residential new construction and remodel projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9 inch throat dimension for standard oval duct stack connections\u003c\/li\u003e\n  \u003cli\u003eOval body profile sized at 6x12-7 for compatibility with common oval duct runs\u003c\/li\u003e\n  \u003cli\u003eStackhead design transitions vertical duct stack to register boot or floor outlet\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential and light commercial forced-air distribution systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-construction fitting for residential and light commercial HVAC oval duct systems using a 9 inch throat stackhead with 6x12-7 oval duct sizing.\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 contractor. The air handling system should be shut down and the disconnect locked out before fitting or modifying any duct components. Secure the stackhead to the duct stack using approved sheet metal screws and seal all joints with UL 181-rated duct tape or mastic sealant per local mechanical code requirements. Do not compress or deform the oval profile during installation, as this will reduce airflow and affect system performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThroat Size\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOval Duct Size\u003c\/strong\u003e: 6x12-7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Oval Stackhead\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: SEAL-TITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4235-0961207\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51343982854450,"sku":"4235-0961207","price":23.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553475.jpg?v=1782026236","url":"https:\/\/voomisupply.com\/products\/seal-tite-4235-0961207-oval-stackhead-9-inch-throat","provider":"Voomi Supply","version":"1.0","type":"link"}
