Lambro Industries 164W Double Sided Under Eave Vent 4 Inch

Product Description

The LAMBRO INDUSTRIES 164W is a double-sided under eave vent designed for residential ventilation applications where exhaust ducts terminate through a soffit or eave. The unit is finished in white and adapts to either 4-inch or 6-inch exhaust ducts using the included 6-inch to 4-inch transition collar. Two removable screens are integrated to block birds and squirrels from entering the duct system. This type of fitting is typically installed by HVAC technicians, roofers, or general contractors during new construction or exhaust system retrofits.

The 164W suits residential installations where bathroom exhaust fans, range hoods, or similar low-pressure exhaust systems terminate through the eave or soffit. The double-sided design allows it to blend into the eave profile from multiple viewing angles. The white finish coordinates with standard painted soffit material. The included transition collar and dual screens make this a complete termination assembly that reduces the need for separate field-sourced components.

Key Features

• Adapts to 4-inch or 6-inch exhaust ducts via included transition collar
• Double-sided design for a finished appearance under the eave
• White finish suited for standard painted soffit installations
• Two removable screens block birds and squirrels from entering the duct
• Complete assembly includes vent, two screens, and a 6-inch to 4-inch transition collar

Compatibility

Designed as an OEM-style termination fitting for residential exhaust duct systems that exit through a soffit or eave using 4-inch or 6-inch round duct.

Installation Notes

Installation is typically performed by an HVAC technician or contractor. Power down any connected exhaust fan before making duct connections. Ensure the duct run is fully supported and that the transition collar is secured with appropriate duct fasteners and foil tape per local mechanical code requirements. Do not obstruct the screens during installation, as unobstructed airflow is required for proper exhaust function.
