It is a rectangular sheet metal fitting used to change direction in low-pressure supply and return air duct systems. The shortway orientation means the turn is made along the narrow dimension of the duct cross-section, keeping the fitting compact in tight mechanical chases. At 28 inches by 8 inches on both the inlet and outlet, this fitting handles a full-size trunk run without reducing duct area through the transition. HVAC sheet metal installers and duct fabricators work with this component during rough-in on residential and light commercial forced-air systems.\u003c\/p\u003e\n\u003cp\u003eThis trunk duct angle is sized for rectangular duct trunk lines in forced-air heating and cooling systems. The vertical, shortway configuration is commonly installed where overhead or wall clearances limit how far a fitting can extend in the longway direction. The 28 inch by 8 inch profile fits standard trunk duct runs and is appropriate for both new construction and retrofit work where a 45-degree directional change is needed in the main supply or return trunk.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree angle provides a gradual directional change to reduce turbulence in the airstream\u003c\/li\u003e\n  \u003cli\u003eShortway rectangular configuration suits installations with limited clearance in the longway plane\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in unconditioned attic, crawlspace, and basement environments\u003c\/li\u003e\n  \u003cli\u003e28 inch by 8 inch inlet and outlet dimensions match full-size trunk duct runs without area reduction\u003c\/li\u003e\n  \u003cli\u003eFabricated to ACCA and SMACNA standards for duct construction and airflow performance\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 built to ACCA and SMACNA standards.

Power down the air handling unit and close the system before cutting into or connecting to an existing duct run. Seal all joints with approved duct sealant or UL 181-listed tape per code. Do not use sheet metal screws in locations that will obstruct airflow inside the fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Vertical, Shortway, Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A\u003c\/strong\u003e: 28 inches length x 8 inches width\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B\u003c\/strong\u003e: 28 inches length x 8 inches width\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\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: 15_28X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284033700146,"sku":"15_28X8","price":71.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277301.jpg?v=1781066715","url":"https:\/\/voomisupply.com\/products\/southwark-metal-15_28x8-trunk-duct-angle-45-degree-28x8","provider":"Voomi Supply","version":"1.0","type":"link"}
