Abstract
A handhole cover includes a body adapted to cover a handhole. The body has a front surface, a rear surface, and a peripheral edge. Engagement members protrude rearwardly and outwardly from the rear surface adjacent to the peripheral edge. The engagement members are adapted to engage a peripheral edge of the handhole and are spaced about the peripheral edge to provide a secure engagement of the body in the handhole. At least one of the engagement members is a rotatable locking member having a helical engagement surface. The rotatable locking member is selectively rotated between a locking position and a release position.
