Abstract
A lightweight plastic cover for an electric handhole or pullbox having a plurality of vertical channels in a circular array at a radius about halfway from the center to the circumference. The channels allow the cover to bend when a large weight is applied and to rebound when the weight is removed. The cover may also have a second circle of vertical channels for strength nearer the center and horizontal channels crossing the center for added strength. The cover has a metal plate attached in the center for finding the cover with a metal detector and may also have a GPS device for locating it. The electric handhole or pullbox may have an open bottom portion with a ledge around the circumference for helping to set and maintain the electric handhole or pullbox at a desired depth. The cover may have extendable handles for ease of holding.
