ABSTRACT:
A curb box cover assembly includes a covering member having a plurality of first openings for the passage of street water. Also, second opening(s) are provided on the covering member which cooperate with a clamping device to secure the covering member to the catch basin. The clamping device includes one clamp member which includes a first and second contact member connected by a transition member of prescribed thickness. The clamp member rotationally mounts on a pivot member. The pivot member includes a threaded opening to receive a bolt member which is advanced into the threaded opening by an operator's action. The pivot member rotates in response to the operator's action so that the clamp member rotates from a first position to a second position at which the clamp member secures the covering member to the catch basin opening. The contact members can rotate independently of each other to accommodate irregularities in the interior surface of the catch basin.
