30"L x 30"W x 12"H black galvanized vent screen keeps raccoons, opossums, squirrels out of your attic
Many roof vents are made from plastic material with simple window-type screening or no screening at all. Animals can chew through these screens and enter your attic, where they may destroy wiring, cause leaks or other damage. This 30"L x 30"W x 12"H Roof VentGuard fits over static vents and power ventilators to eliminate intruders. Made from heavy-duty 18-gauge expanded metal mesh with a black painted galvanized finish. USA made.
NOTE: Animal control screens should only be installed by qualified roofing or siding contractors.
