Designed for use in low-pressure HVAC ductwork systems, this elbow redirects airflow at a right angle within round duct runs. The 4-inch diameter inlet and outlet dimensions make it a standard fit for residential and light commercial supply and return branches. Licensed HVAC technicians and sheet metal workers install this fitting as part of forced-air distribution systems where direction changes are required. Compliance with ACCA and SMACNA standards confirms it meets recognized industry fabrication and performance criteria.\u003c\/p\u003e\n\u003cp\u003eThis elbow is suited for residential and light commercial forced-air HVAC duct systems requiring a 90-degree directional change in 4-inch round ductwork. Typical applications include supply air branch takeoffs, return air connections, and trunk-to-branch transitions. It is commonly installed in attic, crawlspace, basement, and in-wall duct runs where space constraints or layout requirements demand a right-angle turn. Sheet metal contractors and HVAC technicians working on new construction or retrofit duct systems will find this a direct-fit component for standard 4-inch round duct configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree angle for right-angle directional changes in round duct systems\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction provides corrosion resistance in HVAC environments\u003c\/li\u003e\n  \u003cli\u003e30 gauge material thickness meets SMACNA and ACCA fabrication standards\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter on both inlet and outlet for consistent round duct sizing\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct system components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for use with standard 4-inch round ductwork in residential and light commercial forced-air HVAC systems built to SMACNA and ACCA specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal worker in accordance with SMACNA duct construction standards and local mechanical codes. Shut down the air handling system before disconnecting or modifying any duct sections. Sheet metal screws and foil-backed mastic or UL 181-listed duct tape are typically used to secure and seal the elbow at both connections. Wear appropriate cut-resistant gloves when handling sheet metal edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A (Inlet Diameter)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B (Outlet Diameter)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 30 Gauge\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: 90-30GA_4IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284002275634,"sku":"90-30GA_4IN","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276930.jpg?v=1781065675","url":"https:\/\/voomisupply.com\/products\/southwark-metal-90-30ga_4in-round-duct-elbow-90-degree-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
