The FAMCO CSV6WH4FT is a continuous soffit inlet vent designed to provide consistent, low-profile intake airflow along the underside of a roof eave. Constructed from metal and finished in white, this vent measures 6 inches in width and comes in a 4-foot length, making it well suited for new construction and retrofit attic ventilation work. It installs flush into the soffit panel to allow outside air to enter the attic space as part of a balanced passive ventilation system. Roofing contractors, general contractors, and experienced installers typically handle this fitting.
This soffit vent is used in residential attic ventilation systems where continuous intake airflow is needed along the eave line. The 6-inch width and 4-foot run length make it appropriate for standard soffit bays on homes with wood, vinyl, or aluminum soffit panels. It pairs with ridge vents or high exhaust vents to create a balanced intake-exhaust ventilation path that helps manage attic heat and moisture year-round.
Designed as an OEM-style replacement or new-installation soffit inlet vent for residential attic ventilation systems requiring a 6-inch continuous soffit vent profile.
Installation is typically performed by roofing or general contractors following local building code requirements for attic ventilation ratios. Power down any attic-mounted electrical equipment and use appropriate fall-protection measures before working at eave height. The soffit panel must be cut to the correct opening width before securing the vent in place. Do not block the vent screen with insulation baffles or other material after installation, as restricted intake airflow reduces the effectiveness of the ventilation system.
