It features a single-piece construction with vertical adjustable face bars that let technicians direct airflow where it is needed. The unit ships in a nominal 14 x 4 inch size and measures 15.875 inches by 2.25 inches by 5.875 inches overall. HVAC installers and service technicians rely on this type of register to manage conditioned air distribution in offices, retail spaces, and light commercial buildings. The steel body is finished in bright white enamel, making it easy to match standard ceiling and wall trim. The multi-shutter damper provides horizontal adjustable control over airflow volume, giving the installer a simple way to balance the system after installation. Fin spacing is 0.75 inches, which supports even air distribution across the face of the register. Single deflection keeps the airflow pattern consistent and predictable. The actuation type is a horizontal adjustable multi-shutter valve, which is a common and reliable damper mechanism found in commercial-grade supply registers. This register is part of the Hart Cooley 821 series, a line known among HVAC professionals for durable steel construction and clean white enamel finishes that hold up in high-traffic commercial environments. Whether you are replacing an existing unit or completing a new installation, the 821-14x4 is a straightforward drop-in choice for standard sidewall supply openings in light commercial ductwork systems. Contractors, mechanical installers, and HVAC service teams working on forced-air systems will find this register easy to install and reliable in daily operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAdjustable vertical face bars for precise horizontal airflow direction control\u003c\/li\u003e\n\u003cli\u003eMulti-shutter damper allows volume adjustment without additional damper hardware\u003c\/li\u003e\n\u003cli\u003eSteel construction with bright white enamel finish built for light commercial use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Hart Cooley 821-14x4 sidewall supply register combines steel durability with a clean white enamel finish and built-in multi-shutter damper, making it a reliable choice for light commercial HVAC installations that require both airflow control and a professional appearance.\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: 821-14x4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 821\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegister Type\u003c\/strong\u003e: Sidewall, 1-Piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 14 inches x 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Dimensions\u003c\/strong\u003e: 15.875 inches x 2.25 inches x 5.875 inches\u003c\/li\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 Enamel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Bar Style\u003c\/strong\u003e: Vertical Adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation Type\u003c\/strong\u003e: Horizontal Adjustable Multi-Shutter Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Multi-Shutter Damper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFin Spacing\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Light Commercial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 per Case\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51121098555698,"sku":"821-14X4","price":41.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/821__Supply_register_w_adj_vert_blades_with_damper_b594.jpg?v=1777748340","url":"https:\/\/voomisupply.com\/products\/hart-cooley-821-14x4-supply-register-with-adjustable-vertical-blades-14-x-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
