Abstract
A roof vent (or other opening closure means) for a grain bin is disclosed. Generally, a grain bin has a cylindrical bin body and a conical roof. The roof includes a plurality of wedge-shaped panels secured together in side-to-side relation and often one or more of these panels has an opening therein for accommodating a roof vent. A flange is provided on the roof panel defining an opening in the roof panel with the flange being sealably (preferably integrally) formed with the roof panel. The flange extends outwardly so as to prevent water flowing down the slope of the roof from entering into the opening.
