ABSTRACT:
A cover for a handhole of a utility pole is provided. The cover includes a plate with a bolt passing therethrough and a back bracket threaded to the bolt. The back bracket is configured to engage an inwardly extending lip formed on a periphery of the handhole opening. A plate includes a recess which is directed inward towards the back bracket. The bolt passes through a hole in a floor of the recess. The recess inhibits unauthorized access to a head of the bolt. A spring is interposed between a head of the bolt and the floor which biases the back bracket toward the cover. The back bracket remains in contact with the inwardly extending lip of the handhole opening unless the head of the bolt is depressed, compressing the spring to allow the back bracket to be rotated.
