ABSTRACT:
A ventilation opening closure to close off a standard opening in a support structure such as a roof or wall includes a base and a cover plate. The base comprises a base ring, a seal ring between the base ring and the support structure, and a bevel-shaped seal ring to align and seal the cover plate with the base ring. The closure may include a pair of complementary hinges that the closure can be opened to the right or to the left. Alternatively, rather that the second hinge, the closure may include a latch means to more quickly shut the closure.
