ABSTRACT:
A locking device for securing a manhole cover support insert or a grate cover support insert to a utility access frame is disclosed. The locking device includes a plurality of rotatable locking members which are connected to the support insert. The locking members are rotatable between a position where they rest inside the perimeter of the utility access hole and a locking position outside the perimeter of the utility access hole. The locking members may be rotated from an easy to reach position above the utility access hole by turning the exposed head of a bolt. The locking members are stopped from rotating at their locking position by engagement with a stop. From their locking position, the locking members may be axially moved by further rotation of the bolt to lock the support to the frame.
