It measures 6 x 6 inches and is constructed from extruded aluminum with a bright white enamel finish. Return air grilles are a critical part of any forced-air HVAC system. They allow air to flow back to the air handler or furnace for reconditioning. Without proper return airflow, systems lose efficiency and can develop pressure imbalances that shorten equipment life. This grille is built to handle that job reliably. The RH45 Series is known among HVAC installers and service technicians for its clean look and solid construction. The extruded aluminum body resists warping, corrosion, and damage from normal handling. The bright white enamel finish blends with standard wall and ceiling surfaces in residential settings. The 3\/4 inch blade spacing provides consistent airflow while keeping the interior of the duct system out of view. At 6 x 6 inches, this grille fits standard small return air openings commonly found in hallways, bedrooms, and utility spaces. HVAC technicians use return grilles like this one during new installations, system retrofits, and replacement projects. The aluminum construction keeps the grille lightweight, making it easy to work with during installation. It can be mounted in walls or ceilings depending on the duct layout. This grille is a straightforward, durable solution for return air applications where a clean appearance and dependable airflow performance are both required.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eExtruded aluminum construction resists warping and corrosion over time\u003c\/li\u003e\n\u003cli\u003eBright white enamel finish suits standard residential wall and ceiling surfaces\u003c\/li\u003e\n\u003cli\u003e3\/4 inch blade spacing delivers consistent return airflow with a clean appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Hart Cooley 63999 RH45 Series return air grille provides reliable airflow performance in a 6 x 6 inch aluminum frame with a bright white finish, making it a practical choice for residential HVAC return air installations.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\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: 63999\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RH45 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 6 x 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrille Blade Spacing\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Extruded Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright White Enamel\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51120884973874,"sku":"63999","price":68.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881211.jpg?v=1777742360","url":"https:\/\/voomisupply.com\/products\/hart-cooley-63999-rh45-series-return-air-grille-6-x-6-inches-bright-white-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
