Builders Best 110555b Micro Louver Eave Vent 4 in

Product Description

The BUILDERS BEST 110555b is a Micro Louver Eave Vent designed for residential ventilation applications requiring a low-profile, weather-resistant termination point. The vent features a 4-inch diameter opening and a 3-inch collar, making it compatible with standard flexible or rigid duct runs from bathroom exhaust fans and fresh air intake systems. Contractors and installers use this vent at eave or soffit locations where a clean exterior profile is needed. The louvered face allows airflow while limiting intrusion from wind, rain, and pests, keeping the duct path clear and functional over time.

This eave vent suits residential construction and retrofit projects where bathroom exhaust fans or fresh air supply ducts terminate through the eave or soffit area. It is appropriate for new builds and replacement installs alike. The 3-inch collar accommodates standard duct connections, while the 4-inch overall diameter fits common eave penetrations. This product was previously sold under the Pro-Vent Eave Vent designation and carries forward the same form and function under the current part number 110555b, superseding the earlier MPN 110555.

Compatibility

Designed as an OEM-style replacement eave vent for residential bathroom exhaust fan and fresh air intake duct terminations using 3-inch collar duct connections. Previously cataloged as MPN 110555 under the Pro-Vent Eave Vent name.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or qualified contractor following local mechanical code requirements. Shut off the associated exhaust fan or air handler before making duct connections. Ensure the collar is fully seated and sealed to the duct to prevent conditioned air loss or moisture infiltration into the soffit cavity. Follow local building codes for exterior vent placement and clearance from obstructions.
