Glued a screen inside each one and topped off the vent which was sealed at the roof line with a multi-size"rubber" vent boot flashing, since they don't make flashings specifically for ribbed metal roof.

Got this to a job site only to discover it was improperly manufactured and even moderately wind-driven rain would have gone into the vent. Maybe this simply got past quality control--I didn't notice the problem when purchasing dozens of different items.

Rated 4 out of 5 by from Nice I had to improve the product after I purchased it. I installed screens in the air holes, primed it and matched the color with the color of my roof. The product is sturdy. After the improvements, I like the product.

Rated 4 out of 5 by from Great job and looks great too. This was for a gas furnace vent. Did not want to spend a lot of money but wanted something that looked decent too. Both needs were met.

Rated 5 out of 5 by from Good Purchase, the problem was corrected! Birds were getting into my exhaust vent on the roof. The product was ready to install and didn't have any problems with it.
