Constructed from hot-dip galvanized steel, this Air-Tite saddle fitting provides a secure, sealed branch tap off rectangular or round trunk ductwork. The saddle-style design seats firmly against the main duct and is field-cut to fit, allowing HVAC technicians to create clean, low-leakage branch runs during installation or retrofit work. It meets applicable ACCA and SMACNA standards for sheet metal duct construction.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial forced-air systems where a branch takeoff is needed from a main supply trunk. Typical installations include adding a new supply run to an existing trunk line, extending duct systems during a renovation, or replacing a damaged fitting in an existing layout. The 4-inch round outlet suits standard 4-inch round flex or rigid branch ducts commonly used for individual room supply drops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot-dip galvanized steel construction resists corrosion in attic, crawlspace, and basement environments\u003c\/li\u003e\n  \u003cli\u003eAir-Tite saddle design minimizes air leakage at the branch connection point\u003c\/li\u003e\n  \u003cli\u003e4-inch round outlet connects to standard 4-inch round flex or rigid branch duct\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA fabrication and installation standards\u003c\/li\u003e\n  \u003cli\u003eSaddle-style mounting allows field installation on existing trunk ductwork without full duct disassembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential and light commercial sheet metal duct systems requiring a 4-inch round saddle branch takeoff.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut down the air handling unit and confirm the system is de-energized before cutting into existing ductwork. Field-cut the trunk duct opening to match the saddle outlet size and secure the fitting using sheet metal screws and UL 181-rated mastic or foil tape in accordance with SMACNA guidelines. All duct joints and seams should be sealed to minimize system air leakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot-Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Air-Tite Saddle Round Takeoff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ATTRP_4IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284019937586,"sku":"ATTRP_4IN","price":15.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278210.jpg?v=1781066248","url":"https:\/\/voomisupply.com\/products\/southwark-metal-attrp_4in-duct-saddle-takeoff-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
