<p>Anytime a container is used for storage of household items, heavy machinery, automobiles, dry goods, chemicals, or pressurized gases, superior ventilation is critical. The Louvered Vent provides that! This new design allows for superior ventilation of your shipping container, thereby reducing heat, moisture, and fume accumulation inside. Each vent comes with an integrated pest screen with 1,290 - 1/4” (6.4mm) diameter holes. Eleven low-profile louvers keep rain out. The 1.5” flange wraps around the entire vent, including top and bottom, to ensure a comprehensive seal during installation—this is important! Powder-coated in orange, dark gray or white. This unit is designed to be bolt-on so no welding or painting is required. Installation can be done in less than 30 minutes.</p>
