Abstract
A manhole cover assembly is adapted to be received in an opening in a frame enclosing a vault chamber. A manhole cover is fit into the opening. A pair of lugs are mounted to an underside of said manhole cover on opposite sides thereof. Each lug has a portion projecting radially out in a first position so as to engage a fixed feature of said frame. At least one of said lugs is connected to a pivotable member having an upper end projecting up through said manhole cover so that said upper end is engageable to be able to be rotated and cause rotation of said lug therewith between the first position and a second position with said lug not projecting radially out such that the lug radially clears said fixed feature of said frame to allow said manhole cover to be moved up and out of said frame opening.
