Constructed from hot dip galvanized steel at 28 gauge, this rack opens on the short side for filter access in tight return air installations. It fits a 16-inch by 20-inch filter opening and is built to the dimensional and fabrication standards set by ACCA and SMACNA. HVAC technicians and sheet metal contractors install this rack directly into the return air duct to create a serviceable filter slot without field fabrication.\u003c\/p\u003e\n\u003cp\u003eThis filter rack is used in return air duct assemblies where a dedicated filter slot is needed at a 16-inch by 20-inch opening. It is suited for residential forced-air systems and light commercial applications where return air filters are installed within the duct run rather than at a grille or air handler cabinet. The short-side opening design allows installation in applications where clearance is limited on the long dimension of the duct.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHot dip galvanized steel construction resists corrosion in return air environments\u003c\/li\u003e\n  \u003cli\u003e28 gauge material thickness meets SMACNA sheet metal fabrication standards\u003c\/li\u003e\n  \u003cli\u003eOpens on short side for filter access in constrained duct installations\u003c\/li\u003e\n  \u003cli\u003eAccepts standard 1-inch filters in a 16-inch by 20-inch size\u003c\/li\u003e\n  \u003cli\u003eFabricated for direct integration into sheet metal return air duct systems\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal component for installation in return air duct systems requiring a 16-inch by 20-inch filter rack opening with a 1-inch filter depth.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal contractors. The system should be powered down and the air handler shut off before cutting into an existing return air duct or installing the rack in new construction. Sheet metal screws and approved HVAC foil tape or mastic sealant are typically used to secure and seal the rack to the duct. Work should conform to SMACNA duct construction standards and local mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 16 inches x 20 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\u003eMaterial Thickness\u003c\/strong\u003e: 28 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Return Air\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpening Side\u003c\/strong\u003e: Short Side\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: FR_16X20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283908919602,"sku":"FR_16X20","price":31.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278397.jpg?v=1781063008","url":"https:\/\/voomisupply.com\/products\/southwark-metal-fr_16x20-duct-filter-rack-16x20-in","provider":"Voomi Supply","version":"1.0","type":"link"}
