Four Inch Insect Vent Screens

Our PVS-IS4 vent screen has an outside diameter of 4.470″ and is designed to fit inside any standard 4″ vent termination hub or coupling to provide complete protection from animals, debris and insects. Because 4″ vent screens are not commonly used in residential applications, we recommend viewing our sizing page for information regarding fitment.
