It transitions from a 19 x 14 inch opening to a 23 x 21 inch opening, making it a practical solution for air distribution layouts where duct geometry changes between the air handler or furnace and the main trunk line. The unit ships with R-6 insulation, which helps reduce heat gain and loss through the plenum body. At 11.22 pounds, it is a substantial sheet metal component intended for professional installation in residential or light commercial ductwork systems.\u003c\/p\u003e\u003cp\u003eThis transition plenum fits applications where a duct system requires a step-up or step-down connection between two rectangular openings. It is suited for new construction and retrofit installations in residential forced-air systems, particularly where the equipment cabinet outlet does not match the existing trunk duct dimensions. The R-6 insulation rating makes it appropriate for installations in unconditioned spaces such as attics, crawlspaces, and garages where energy code compliance for duct insulation is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTransitions from 19 x 14 inches to 23 x 21 inches to connect mismatched duct openings\u003c\/li\u003e\n\u003cli\u003eR-6 insulation factory-applied to reduce thermal loss in unconditioned spaces\u003c\/li\u003e\n\u003cli\u003eSheet metal construction for durability and long service life\u003c\/li\u003e\n\u003cli\u003eWeighs 11.22 pounds for stable, secure installation in duct systems\u003c\/li\u003e\n\u003cli\u003eSuited for residential and light commercial forced-air HVAC applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style transition plenum for rectangular duct systems requiring a connection between a 19 x 14 inch opening and a 23 x 21 inch opening in forced-air HVAC installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Power down the air handling equipment at the disconnect before beginning duct work. Seal all joints with UL 181-rated mastic or metal-backed tape in accordance with local mechanical codes and ACCA installation standards. Support the plenum per local code requirements to prevent stress on adjacent duct connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Dimensions\u003c\/strong\u003e: 19 x 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Dimensions\u003c\/strong\u003e: 23 x 21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Rating\u003c\/strong\u003e: R-6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MCDANIEL METALS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TR2-18T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MCDANIEL METALS","offers":[{"title":"Default Title","offer_id":51268147872050,"sku":"TR2-18T","price":79.72,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913287.webp?v=1780700350","url":"https:\/\/voomisupply.com\/products\/mcdaniel-metals-tr2-18t-transition-plenum-r-6-insulated","provider":"Voomi Supply","version":"1.0","type":"link"}
