This fitting provides a secure, low-leak branch connection from a main trunk duct to a branch run, with the built-in damper allowing airflow balancing without the need for a separate balancing device. It is sized at 14 x 12 inches and is typically installed by licensed HVAC sheet metal technicians and mechanical contractors during new construction or system retrofits.\u003c\/p\u003e\n\u003cp\u003eThe MTD1412 is suited for residential and light commercial forced-air HVAC systems where round branch takeoffs are required from rectangular or round main trunk ducts. The conical spin-in design seats firmly into a field-cut or knockout opening in the trunk, creating a reliable connection point. The integrated damper blade allows the installing technician to balance supply airflow across multiple branch runs after system commissioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConical spin-in collar seats securely into the trunk duct opening for a tight, low-leak fit\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper blade enables airflow balancing without separate hardware\u003c\/li\u003e\n  \u003cli\u003eMetal construction provides durability in standard forced-air duct systems\u003c\/li\u003e\n  \u003cli\u003e14 x 12 inch sizing accommodates common branch duct configurations\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard round branch duct connections off rectangular or round trunk lines\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 metal forced-air duct systems requiring a conical spin-in takeoff with damper at a 14 x 12 inch opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified HVAC technicians or sheet metal mechanics. The system blower should be de-energized and the air handler powered down completely before cutting into an existing trunk duct. The spin-in collar is inserted into the field-cut opening and rotated to lock in place per standard sheet metal practice. Seal all connections with UL 181-rated mastic or listed metal duct tape in accordance with applicable mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Conical Spin-In Takeoff with Damper\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: MTD1412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51345944969522,"sku":"MTD1412","price":138.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552916.jpg?v=1782067103","url":"https:\/\/voomisupply.com\/products\/air-flow-products-mtd1412-conical-spin-in-takeoff-with-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
