It is designed for branch duct connections off a main trunk line in forced-air HVAC distribution systems. The Air-Tite saddle design provides a secure, low-leakage fit against the main duct wall, while the built-in damper allows airflow balancing at the branch point. Licensed HVAC technicians and sheet metal installers handle this fitting as part of new construction or retrofit duct fabrication work.\u003c\/p\u003e\u003cp\u003eThis takeoff is used in residential and light commercial forced-air systems where round branch runs are required. The saddle-style mounting seats directly over a cut opening in the main rectangular or round trunk duct. The damper allows the installer to throttle airflow to individual zones or rooms, making this fitting well-suited for systems that require zone balancing or room-by-room airflow adjustment during commissioning. It is installed where a 12-inch round branch duct departs the supply or return trunk.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-inch diameter round outlet sized for standard round duct and fittings\u003c\/li\u003e\n\u003cli\u003eHot-dip galvanized steel construction for corrosion resistance in air distribution environments\u003c\/li\u003e\n\u003cli\u003eIntegrated damper for airflow balancing at the branch takeoff point\u003c\/li\u003e\n\u003cli\u003eAir-Tite saddle design for a snug, low-leakage seat against the main trunk duct\u003c\/li\u003e\n\u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fabrication and installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air duct systems requiring a 12-inch round saddle-style branch takeoff with damper.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling unit and verify the system is de-energized before cutting into the trunk duct or securing the saddle fitting. Secure the takeoff to the trunk duct with sheet metal screws and seal all joints with UL-listed duct sealant or mastic per ACCA Manual D and applicable local codes. Set the damper position during system commissioning and verify balanced airflow before closing out the installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Air-Tite, Saddle, Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dip Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInclusions\u003c\/strong\u003e: Damper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ATDRP_12IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283954958642,"sku":"ATDRP_12IN","price":34.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278817.jpg?v=1781064118","url":"https:\/\/voomisupply.com\/products\/southwark-metal-atdrp_12in-duct-takeoff-12-inch-round","provider":"Voomi Supply","version":"1.0","type":"link"}
