    Description says "built in screen" but the specification shows none - and the in stock ones at my local HD have no screen either. Is there a screen if I order online?

    Thank you for your question. These do not have built in screens. This was added in error and we are working with Home Depot to correct.

            This product is a good start, but I need to modify it a little.to keep bugs out. The openings are wide enough to let lots of bugs into the attic. I'm going to add some screen behind the louvers to resolve the bug issue. Other ventilation equipment for attics already come with screens to keep most of the bugs out.
