ABSTRACT:
A one-piece, unitary manhole cover has dual lifting ports that drain through the outer circumferential edge of the cover. A lifting channel runs from the interior of the upper face out to the outer circumferential edge. A lifting bar spans the lifting channel and defines an ergo lifting port and a pry bar lifting port. Both the ergo lifting port and the pry bar lifting port drain through the outer circumference of the manhole cover.
