Built from all-steel construction with fins spaced at 0.5 inches and set at a 40-degree angle, this grille delivers exceptional free area for efficient return airflow. The 5\/16-inch margin turnback provides a clean, finished look against the wall or ceiling surface. A bright white powder finish makes it suitable for standard painted interior applications. HVAC technicians and sheet metal contractors typically specify this grille for return air duct openings in forced-air systems.\u003c\/p\u003e\u003cp\u003eThis return air grille fits a 16-inch by 10-inch duct opening and is well-suited for residential forced-air HVAC installations as well as light commercial applications. The fixed-fin design with 0.5-inch fin spacing optimizes static pressure performance across the return side of the air handler. It installs flush against drywall, plaster, or wood surfaces using the integrated margin turnback to conceal the duct edge. Interior designers and HVAC installers alike specify white-finish grilles for standard residential return air locations in walls and ceilings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAll-steel construction for long-term durability in return air applications\u003c\/li\u003e\n\u003cli\u003eFins spaced at 0.5 inches and fixed at 40 degrees for high free-area performance\u003c\/li\u003e\n\u003cli\u003e5\/16-inch margin turnback conceals duct edges for a clean finish\u003c\/li\u003e\n\u003cli\u003eBright white finish compatible with standard interior paint schemes\u003c\/li\u003e\n\u003cli\u003eSized for a 16-inch by 10-inch duct opening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation return air grille for standard 16-inch by 10-inch duct openings in residential and light commercial forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by an HVAC technician or sheet metal contractor as part of duct system rough-in or retrofit work. Power down the air handler and ensure the system is not operating before removing an existing grille or securing the new one. The grille mounts mechanically to the duct collar or wall surface; do not over-tighten fasteners against the steel frame to avoid distortion. Verify the duct opening dimensions match the grille neck size before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 16 inches x 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFin Spacing\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFin Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMargin Turnback\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6721610w\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51383310549298,"sku":"6721610W","price":36.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674316.webp?v=1782593021","url":"https:\/\/voomisupply.com\/products\/hart-cooley-6721610w-steel-return-air-grille-16x10","provider":"Voomi Supply","version":"1.0","type":"link"}
