Builders Best 111869a Round Soffit Vent 4 Inches

Product Description

The BUILDERS BEST 111869a is a plastic round soffit vent designed for 4-inch duct terminations in residential ventilation applications. Molded from UV-stabilized polymer resin, this vent resists sun degradation and maintains structural integrity in exposed exterior locations. The extra-long collar provides a secure friction fit over standard 4-inch round duct, reducing the need for additional fasteners during installation. A molded-in mesh screen blocks pest entry and debris while maintaining airflow. HVAC technicians and general contractors install this vent as the exterior termination point for bathroom exhaust fans, dryer-alternative venting setups, and similar low-pressure round duct runs.

This soffit vent is suited for residential new construction and retrofit projects where a 4-inch round duct exits through a soffit, eave, or similar horizontal surface. It provides a clean, weather-resistant termination for exhaust duct systems routed through attic spaces. The friction-fit collar design allows for straightforward field installation without specialty tools. Applications include bathroom fan exhaust, kitchen range hood auxiliary runs, and general mechanical ventilation where a 4-inch termination point is required at the soffit line.

Key Features

• UV-stabilized polymer resin construction resists sun exposure and outdoor weathering
• Extra-long collar improves duct engagement and reduces the chance of pullout
• Secure friction fit over standard 4-inch round duct eliminates need for additional clamps
• Molded-in mesh screen provides integrated pest and debris barrier
• Designed for horizontal soffit or eave-mounted duct termination

Compatibility

Designed as an OEM-style termination vent for residential 4-inch round duct exhaust systems exiting through a soffit or eave surface.

Installation Notes

Installation is typically performed by HVAC technicians or general contractors during rough-in or finish stages of construction. Shut down the associated exhaust fan or ventilation equipment before connecting ductwork to the collar. Ensure the 4-inch duct end is clean and free of obstructions before seating it into the friction-fit collar. Local building codes, including applicable mechanical and energy codes, may require dampered terminations for certain exhaust applications, so verify local requirements before installation.
