Abstract
A cover comprises a frame having first and second sides oppositely disposed from one another. The frame defines a perimeter. A first plate is attached to the first side of the frame. A portion of the first plate extends outwardly from the perimeter and forms an engagement surface surrounding the frame. A second plate is attached to the second side of the frame. The cover has at least one lifting lug attached to the second plate. A gasket is attached to the engagement surface of the first plate. The cover is positioned within an opening to a vault. A portion of the interior surface of the vault forms a peripheral surface surrounding the opening. The cover is drawn against the opening so as to engage the gasket attached to the engagement surface of the cover with the peripheral surface surrounding the opening.
