It is designed to close off the open terminus of a rectangular trunk duct section, preventing airflow bypass and maintaining system static pressure. This type of fitting is a standard component in forced-air HVAC distribution systems. HVAC sheet metal installers and ductwork mechanics fit this cap during new construction, system modification, or whenever a trunk run is terminated or capped off during phased installation.\u003c\/p\u003e\u003cp\u003eThis end cap is suited for residential and light commercial forced-air duct systems where a 22-inch by 10-inch rectangular trunk duct requires closure. It is appropriate for use in supply or return trunk applications where the duct run must be sealed at the endpoint. The hot-dip galvanized steel construction makes it suitable for installation in unconditioned spaces such as attics, crawlspaces, and mechanical rooms where moisture resistance is a factor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e22 inches by 10 inches nominal size fits standard rectangular trunk duct of the same dimension\u003c\/li\u003e\n\u003cli\u003eHot-dip galvanized steel construction provides corrosion resistance in unconditioned and semi-conditioned spaces\u003c\/li\u003e\n\u003cli\u003eTrunk-type fitting closes the open end of a rectangular duct run to maintain system pressure balance\u003c\/li\u003e\n\u003cli\u003eMeets applicable ACCA and SMACNA standards for sheet metal ductwork fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sheet metal fitting for rectangular trunk duct systems measuring 22 inches by 10 inches, fabricated to ACCA and SMACNA standards for forced-air HVAC ductwork.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed HVAC technician or qualified sheet metal mechanic. The air handling system should be powered down and the blower de-energized before fitting any duct termination cap. Secure the end cap to the duct with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA guidelines. Do not rely on duct tape alone as a long-term air seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 22 inches x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Trunk\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: 21_22X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284138295602,"sku":"21_22X10","price":19.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277205.jpg?v=1781069541","url":"https:\/\/voomisupply.com\/products\/southwark-metal-21_22x10-trunk-duct-end-cap-22x10","provider":"Voomi Supply","version":"1.0","type":"link"}
