Fabricated from hot dip galvanized steel, this vertical angle fitting directs airflow through a 45-degree turn along the short dimension of the duct. It is sized at 18 inches by 10 inches on both the inlet and outlet, making it a same-size transition fitting rather than a reducing piece. HVAC sheet metal mechanics install this component when a duct run requires a 45-degree directional change without altering duct dimensions. It conforms to ACCA and SMACNA standards for commercial and residential low-pressure duct systems.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for rectangular trunk duct installations in forced-air heating and cooling systems. The shortway orientation means the turn is made across the narrow (10-inch) dimension of the duct, which is common in tight ceiling plenums or crawlspace runs where vertical clearance is limited. Both the inlet and outlet measure 18 inches by 10 inches, so no transition collar or offset fitting is needed at the connection points. Sheet metal contractors handling new construction, retrofit, or mechanical room duct fabrication will find this fitting appropriate for low-pressure supply and return trunk assemblies built to SMACNA duct construction standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree vertical shortway angle for directional changes along the narrow duct dimension\u003c\/li\u003e\n\u003cli\u003eHot dip galvanized steel construction resists corrosion in conditioned and unconditioned spaces\u003c\/li\u003e\n\u003cli\u003eConsistent 18 x 10 inch dimensions on both ends — no transition required\u003c\/li\u003e\n\u003cli\u003eRectangular profile matches standard trunk duct cross-sections\u003c\/li\u003e\n\u003cli\u003eFabricated to ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-construction fitting for rectangular sheet metal trunk duct systems built to SMACNA and ACCA duct construction standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Shut down the air handling unit and de-energize the system before connecting or modifying any duct section. Secure all joints with sheet metal screws and seal with UL 181-listed duct sealant or mastic per local mechanical code requirements. Verify duct support spacing meets SMACNA hanger and support guidelines for the applicable duct size and pressure class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\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: 18 inches x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize B\u003c\/strong\u003e: 18 inches x 10 inches\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: 15_18X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283981992242,"sku":"15_18X10","price":52.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277310.jpg?v=1781064981","url":"https:\/\/voomisupply.com\/products\/southwark-metal-15_18x10-trunk-duct-angle-18x10-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
