Product details:

This VentGuard stands nine inches tall and measures seven inches square at the base. A black painted, 18 gauge steel mesh cage keeps pests out of your chimney and cannot be chewed through by animals' sharp teeth. Animals that enter your home by way of your chimney vent can cause expensive and dangerous damage to wiring and other components. With this guard in place, you will have a rust-free and attractive shield in place to protect your flue.
