Constructed from solid steel with a white powder-coat finish, this grille fits a 12-inch by 4-inch duct opening and delivers an overall finished face size of 14 inches by 6 inches. The built-in damper allows airflow adjustment directly at the register without additional hardware. Licensed HVAC technicians and finish contractors install this grille during new construction or renovation work where a cleaner, modern aesthetic is required alongside functional air delivery.\u003c\/p\u003e\n\u003cp\u003eThis supply vent is suited for forced-air systems serving bedrooms, living spaces, hallways, and corridors where a low-profile slotted face blends with contemporary or transitional interior finishes. The 12-inch by 4-inch duct size is commonly found in branch runs off residential supply plenums. The unit installs directly over the existing duct boot opening on drywall, plaster, or ceiling surfaces, making it a practical direct-replacement option for standard 12x4 duct openings in both new builds and remodel projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid steel construction with white powder-coat finish for long-term durability\u003c\/li\u003e\n  \u003cli\u003eSlotted face design suits modern and transitional interior aesthetics\u003c\/li\u003e\n  \u003cli\u003eIntegrated damper allows on-register airflow adjustment\u003c\/li\u003e\n  \u003cli\u003eFits 12-inch by 4-inch duct opening with a 14-inch by 6-inch finished face size\u003c\/li\u003e\n  \u003cli\u003eCompatible with wall and ceiling mounting positions\u003c\/li\u003e\n  \u003cli\u003eDirect-replacement sizing simplifies installation in new construction and remodel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-replacement supply vent for standard 12-inch by 4-inch duct openings in residential and light commercial forced-air HVAC systems installed in walls or ceilings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by an HVAC technician or finish contractor. Power down the air handling unit at the disconnect or thermostat before removing the existing grille to prevent debris from entering the duct system. Secure the grille to the wall or ceiling surface using the manufacturer-provided or field-supplied fasteners at the mounting holes. Verify the duct boot opening measures 12 inches by 4 inches before installation to confirm proper fit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 12 inches x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Finished Face Size\u003c\/strong\u003e: 14 inches x 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid steel with white powder-coat finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper\u003c\/strong\u003e: Integrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Position\u003c\/strong\u003e: Wall or ceiling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 16 inches x 8 inches x 4 inches\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: SteelCrest\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BSL12X4SWHH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEELCREST","offers":[{"title":"Default Title","offer_id":51138529820978,"sku":"BSL12X4SWHH","price":75.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305534900_da7e0237-7ff9-4712-90ec-01ef14f0e238.jpg?v=1779826595","url":"https:\/\/voomisupply.com\/products\/steelcrest-bsl12x4swhh-supply-vent-damper-12x4-hvac-grille","provider":"Voomi Supply","version":"1.0","type":"link"}
