Measuring 2.25 inches by 12 inches by 48 inches, this flat duct fitting channels conditioned air vertically through wall cavities to floor or baseboard registers. Its galvanized steel construction resists corrosion and holds its shape under typical residential duct pressures. HVAC installers use this type of fitting when routing supply air in tight wall spaces where round duct or larger rectangular duct is not practical. The 48-inch length covers a standard stud-bay run in a single section, reducing the number of joints in the assembly.\u003c\/p\u003e\n\u003cp\u003eWall stack ducts like the 200-224 are used in new construction and retrofit residential HVAC installations. The 2.25-inch by 12-inch cross-section fits the narrow depth of a standard 2x4 framed wall cavity, making it a common choice for single-story and multi-story homes where supply runs must travel vertically inside exterior or interior walls to reach floor-level registers. Licensed HVAC technicians and sheet metal contractors install this fitting as part of a low-velocity supply duct system connected to a gas furnace, heat pump, or air handler.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized steel construction for corrosion resistance in concealed wall installations\u003c\/li\u003e\n  \u003cli\u003e2.25 x 12 x 48 inch profile fits standard 2x4 wall cavity depth\u003c\/li\u003e\n  \u003cli\u003e48-inch section length minimizes joints in a single-story wall run\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.80 pounds for easy single-person handling during framing-stage installs\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard wall stack boots and register collars used in residential supply systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for residential forced-air supply duct systems using 2.25-inch by 12-inch wall stack components.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWall stack duct is typically installed by licensed HVAC technicians or sheet metal contractors during the rough-in phase of construction or as part of a duct replacement project. Shut down and lock out the air handler or furnace before modifying any connected duct section. Secure all joints with sheet metal screws and seal with UL 181-listed duct mastic or metal-foil tape in accordance with local mechanical codes. Avoid compressing or crimping the fitting during installation, as deformation reduces airflow cross-section and system efficiency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 2.25 inches x 12 inches x 48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.80 pounds\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: SNAPPY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 200-224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SNAPPY","offers":[{"title":"Default Title","offer_id":51233431552306,"sku":"200-224","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633834.jpg?v=1780099825","url":"https:\/\/voomisupply.com\/products\/snappy-200-224-galvanized-wall-stack-duct-2-25x12x48","provider":"Voomi Supply","version":"1.0","type":"link"}
