The Lambro white plastic universal hinged vent guard is ideal for keeping out pests from entering the outside vent. This guard is used to go over most 3 in and 4 in exhaust vents on-the outside wall. Unlike most vent guards in the market, this guard is hinged for easy access to the vent for cleaning purposes. The plastic vent has a UV additive to prevent premature fading due to the sun.
