Lambro 4.23 in. W X 5.48 in. L White Plastic Wall Louver

The Lambro 4 in. white plastic louvered exhaust wall vent with 11 in. pipe is ideal for venting through the wall for new and replacement installations. This vent is used for clothes dryer exhaust, bath fan exhaust, range hood exhaust and other general venting applications where exhaust air needs to exit to the exterior. The built in flaps prevent back drafts and prevents critters from entering the home through the vent. The plastic vent is made of a polymer resin material and has a UV additive to prevent premature fading due to the sun. Check local building codes prior to installation.
