The Lambro 4 inch white plastic fresh air (hood style) intake wall vent replaces traditional triangle louvered intakes in todays market. The redesigned intake vent is modern and helps prevent water from entering the vent with its hood style design. The fresh air intake vent is for new and replacement installations. The vent frame comes with four screw holes to secure the vent and a caulk-friendly frame for completing the installation. The vent features a removable screen, which enables easy inspection and cleaning. Please check the inside of the vent regularly to prevent the build-up of outside elements, such as leaves and debris. The vents manufacturing material is polymer resin with a UV additive to prevent premature fading caused by sunlight. It would be best to prep the vent before painting it; we recommend plastic paint to paint the plastic vent effectively. Please be sure to check local building codes before installation.
