Abstract
A corrosion-resistant self-locking manhole cover includes a cover plate adapted to rest on a manhole cover support surface of a manhole frame so as to be substantially flush with a top portion of the frame and a surrounding surface. An anchor on the cover plate, which may comprise nonmetallic corrosion-resistant material, is adapted to engage the manhole frame at a first location in a manner that resists lifting of the cover plate proximate to such location. A locking member on the cover plate, which may also comprise nonmetallic corrosion-resistant material, is movable between a locked position and an unlocked position. In the locked position, the locking member is adapted to engage the manhole frame at a second location in a manner that resists lifting of the cover plate proximate to such location. In the unlocked position, the locking member is disengaged from the manhole frame.
