It is a shortway, vertical elbow designed for use in sheet metal ductwork systems where a right-angle turn is required in a confined or space-restricted run. The 20 x 12 inch throat dimensions match both the inlet and outlet, making it a direct inline fitting for rectangular trunk duct assemblies. HVAC sheet metal installers and mechanical contractors use this fitting in low-pressure forced-air distribution systems. Construction meets ACCA and SMACNA standards for sheet metal ductwork fabrication.\u003c\/p\u003e\n\u003cp\u003eThis elbow is used in residential and light commercial forced-air HVAC duct systems. The shortway geometry keeps the elbow compact along the duct run, making it the preferred choice when ceiling clearance or joist bay depth limits the available turning radius. It fits into rectangular trunk duct configurations where maintaining a consistent 20 x 12 inch cross-section through the turn is required. Typical installations include main trunk transitions, horizontal-to-vertical transitions, and branch takeoff setups in attic, basement, or crawlspace duct runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree shortway rectangular elbow for compact right-angle duct turns\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in HVAC environments\u003c\/li\u003e\n  \u003cli\u003eConsistent 20 x 12 inch cross-section on both inlet and outlet\u003c\/li\u003e\n  \u003cli\u003eVertical orientation suits standard trunk duct routing configurations\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA standards for low-pressure sheet metal duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal fitting for rectangular trunk duct systems with a 20 x 12 inch duct size, conforming to ACCA and SMACNA ductwork fabrication standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal mechanics. Power down the air handling unit and close the system before connecting or sealing fittings. Secure all joints with sheet metal screws and seal with mastic sealant or UL 181-listed foil tape per SMACNA guidelines. Follow local mechanical codes for support spacing and hanger requirements on rectangular duct runs.\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\u003eDuct Size A\u003c\/strong\u003e: 20 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size B\u003c\/strong\u003e: 20 inches x 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 90 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Vertical, Shortway, Rectangular\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: 16_20X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283992543538,"sku":"16_20X12","price":72.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277330.jpg?v=1781065341","url":"https:\/\/voomisupply.com\/products\/southwark-metal-16_20x12-trunk-duct-elbow-90-degree-20x12","provider":"Voomi Supply","version":"1.0","type":"link"}
