Superior RV VL100W RV Roof Vent Weather Cover - White

This is a roof vent weather cover for standard 14" x 14" roof vents with small fans or no fan. The UV-Protected, polyethylene plastic cover keeps rain away from your roof vent so you can keep it open in all kinds of weather, allowing you to circulate air in and out of your RV or trailer without fear of water damage. Additionally, the cover protects against strong winds blowing the cover of the vent off it's hinges. While it keeps water out, it lets some light in, so you don't have to feel like you live in a dungeon.
