Lomanco CV4BR Circle Vent 4 Inches Brown Aluminum

Product Description

The LOMANCO CV4BR is a 4-inch round wall vent designed to exhaust moisture from enclosed wall cavities in residential and light commercial construction. Built from heavy-duty aluminum, it resists corrosion and holds up in exterior applications. The brown finish blends with common siding and trim colors, reducing visual impact on the building facade. This vent works by allowing trapped moisture vapor to escape before it causes paint peeling, wood rot, or mold growth inside wall assemblies. It installs with a simple drill pop-in method, requiring no fasteners or adhesive in most applications. Carpenters, siding contractors, and general contractors commonly install this type of vent during new construction or remediation work.

The CV4BR is suited for exterior wall cavity ventilation in wood-framed residential structures and light commercial buildings. It is typically installed in siding or sheathing where moisture accumulation is a concern, particularly in humid climates or in walls adjacent to bathrooms, kitchens, and laundry areas. The drill pop-in installation method makes it practical for retrofit situations where wall cavities need added ventilation without major structural modification.

Installation Notes
