Glad I was able to get Weathered Wood color.

Would Recommend

I’m pleased with my purchase of 2 roof wind turbine vents. But one came with the small black cap loose in the box. When I snap it back in place it pops loose again. I’ll have to add screws to hold it tight. Without it in place rain can come straight into the attic.
