Will it fit my crawl space opening?

It covers a cut opening up to 6-3/4 x 14-3/4 inches and measures 16 x 8 inches overall. Measure your opening before ordering.

The cover with its sliding damper and galvanized screen. The six mounting screws are not included.

Yes. The ABS has UV inhibitors and is paintable, and the gray finish takes paint well.

That is the lowest of the two new prices listed as of November 4, 2026. For a US-made screened cover with a sliding damper, it is a reasonable price.

It is made to the 2012 International Residential Code, chapter 4, section R408, which covers crawl space ventilation.

Can it go on rough concrete?

No. Do not screw it to rough or uneven surfaces; mount it on a flat, sound wall.
