Abstract
In a rectangular utility vault cover a continuous flange on the underside of the cover presses against a sealing material contained in a channel mounted on the vault casing to form a non load bearing seal on the vault cavity. A raised ramp or cam located at each corner of the cover rides upon a raised track on the casing so that the projecting flange does not abrade the sealing material as the cover is slidably removed from the vault casing.
