Built for an 8-inch x 8-inch rectangular duct opening, it features a 4-way deflection pattern that distributes conditioned air in four directions for broader room coverage. An integrated multi-shutter opposed blade damper is mounted directly at the face, allowing manual airflow volume adjustment without additional hardware. Licensed HVAC technicians and service pros install this register as the terminal supply outlet in forced-air distribution systems where directional control and balancing are required at the face.\u003c\/p\u003e\n\u003cp\u003eThis register suits residential forced-air applications in both new construction and retrofit work. The 4-way air pattern makes it well suited for ceiling installations near the center of a room, where spreading airflow evenly across the space improves comfort and reduces hot and cold spots. Sidewall mounting is also supported, giving installers flexibility in duct outlet placement. The multi-shutter damper allows balancing at the register face without returning to the air handler or adjusting trunk dampers, making it practical for room-by-room airflow tuning in rectangular duct systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-way deflection pattern distributes supply air in four directions for improved room coverage\u003c\/li\u003e\n  \u003cli\u003eIntegrated multi-shutter opposed blade damper allows manual airflow volume adjustment at the face\u003c\/li\u003e\n  \u003cli\u003eFits an 8-inch x 8-inch rectangular duct opening\u003c\/li\u003e\n  \u003cli\u003eCompatible with ceiling or sidewall installation configurations\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in residential forced-air systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style supply air register for residential forced-air HVAC systems using rectangular duct with an 8-inch x 8-inch duct opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician as part of a supply air distribution system. Power down the air handling equipment before cutting into ductwork or securing the register to the ceiling or sidewall surface. Ensure the duct rough opening matches the 8-inch x 8-inch specification before securing the register to prevent air bypass around the frame. Adjust the multi-shutter damper after system startup to balance airflow to the space.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 8 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Pattern\u003c\/strong\u003e: 4-Way\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Multi-Shutter Opposed Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Adjustment\u003c\/strong\u003e: Manual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Ceiling or Sidewall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential HVAC Supply Air\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: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 404M8X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51346613698866,"sku":"404M8X8","price":36.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555134.jpg?v=1782085437","url":"https:\/\/voomisupply.com\/products\/rectorseal-404m8x8-4-way-ceiling-sidewall-damper-8x8","provider":"Voomi Supply","version":"1.0","type":"link"}
