A vinyl foundation vent kit from Builders Edge that combines a trim ring, a fixed louver and a molded screen in one package. It measures 18 1/2 by 9 3/8 inches and gives 50 square inches of net free ventilation area, enough for crawl space airflow on most single vents. The clay color and vinyl build suit new construction or remodeling, and the maker says it will not crack, split or fade. The best new price is $39.89 at Millwork.com as of November 4, 2026, and only one store lists it new, so there is little price history to compare against.
