It ships fully assembled with an 11-inch tailpipe, a back-draft flapper, and a riveted tailpipe construction that resists separation during installation. The hood is finished in white and sized for 4-inch duct connections, making it a direct fit for standard residential dryer and bath exhaust applications. Licensed HVAC technicians and plumbers install this type of fitting at the exterior wall penetration to prevent back-drafting and weather infiltration while maintaining proper exhaust flow.\u003c\/p\u003e\u003cp\u003eThis vent hood is suited for residential installations where a 4-inch round duct exits through an exterior wall or soffit. The wide mouth profile helps reduce restriction at the termination point, supporting adequate exhaust velocity for dryer venting and general mechanical ventilation. The included back-draft flapper closes when the system is idle to block cold air, pests, and moisture from entering the duct. It is commonly installed during new construction or as a direct replacement of damaged or deteriorated exterior vent caps.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFully assembled unit ready for installation out of the box\u003c\/li\u003e\n\u003cli\u003e11-inch tailpipe for secure wall-depth insertion\u003c\/li\u003e\n\u003cli\u003eRiveted tailpipe construction for a rigid, durable connection\u003c\/li\u003e\n\u003cli\u003eBack-draft flapper prevents reverse airflow when system is off\u003c\/li\u003e\n\u003cli\u003eWhite finish blends with standard exterior wall surfaces\u003c\/li\u003e\n\u003cli\u003eSized for 4-inch round duct connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation termination fitting for 4-inch round residential exhaust duct systems, including dryer venting and bath fan exhaust.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by an HVAC technician or general contractor during rough-in or retrofit work. Power down the appliance and confirm the duct run is clear before fitting the hood into the wall opening. Exterior penetrations should be sealed around the back plate with an appropriate weatherproof caulk to prevent moisture intrusion. Follow local mechanical codes and manufacturer guidelines for minimum clearances at exterior vent terminations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Connection Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTailpipe Length\u003c\/strong\u003e: 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly\u003c\/strong\u003e: Fully assembled\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: BUILDERS BEST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 110113a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUILDERS BEST","offers":[{"title":"Default Title","offer_id":51383312351538,"sku":"110113A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674178.webp?v=1782593083","url":"https:\/\/voomisupply.com\/products\/builders-best-110113a-wide-mouth-vent-hood-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
