The conical spin-in design allows the fitting to seat securely into a pre-punched or field-cut hole in a rectangular or round trunk duct, creating a low-leakage connection. The built-in damper lets the installing technician balance airflow at the branch level without adding a separate balancing damper. This fitting is installed by sheet metal workers and HVAC service technicians during new construction and retrofit duct work.\u003c\/p\u003e\n\u003cp\u003eThe MTD1614 is suited for residential and light commercial forced-air systems where branch takeoffs are needed along a main supply trunk. The 16-inch trunk connection paired with the 14-inch branch opening makes this fitting appropriate for higher-volume supply runs where adequate airflow delivery to large zones or multiple diffusers is required. It is commonly used in attic, basement, and crawl space duct systems where trunk-and-branch layouts are standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConical spin-in design seats firmly into trunk duct for a secure, low-leakage connection\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper allows airflow balancing at the branch takeoff point\u003c\/li\u003e\n  \u003cli\u003eMetal construction provides durability in both supply and return air applications\u003c\/li\u003e\n  \u003cli\u003e16 x 14 inch sizing suits high-volume branch runs in residential and light commercial systems\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard trunk-and-branch forced-air duct layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spin-in takeoff for standard metal trunk duct systems using conical spin-in fittings in forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or licensed sheet metal contractor. Power down the air handling unit and close the system disconnect before cutting into or modifying any duct section. Use a hole saw or duct punch sized to match the fitting collar for a proper spin-in seat, and secure the fitting with sheet metal screws and mastic sealant or UL 181-rated tape to minimize air leakage. Set the integrated damper position during system commissioning as part of the overall airflow balancing procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrunk Connection Size\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBranch Opening Size\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Conical Spin-In Takeoff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper\u003c\/strong\u003e: Integrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Metal\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: MTD1614\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51342781677874,"sku":"MTD1614","price":161.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552917.jpg?v=1782006422","url":"https:\/\/voomisupply.com\/products\/air-flow-products-mtd1614-conical-spin-in-takeoff-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
