1. A cover member for engaging an anchor in a pre-cast concrete structural member to cover an access pocket depressed into an exterior surface of the pre-cast concrete structural member exposing the anchor for utilization, comprising:
an upper surface including a central dome portion surrounded by a peripheral flange extending around a circumference of the central dome;
a lower surface formed with first and second protrusions positioned to extend downwardly into said access pocket when installed on said pre-cast concrete structural member, said first and second protrusions having a valley formed therebetween;
said first protrusion having a first generally vertical wall terminating in a lower edge at a first level defined as a first dimension from said peripheral flange, said lower edge at least partially defining an opening permitting access internally of said first protrusion;
said second protrusion having a second generally vertical wall terminating in a lower edge at a second level defined as a second dimension from said peripheral flange, said second dimension being smaller than said first dimension; and
a third protrusion supported on said second protrusion and extending downwardly from said second level to said first level, said third protrusion including an access opening smaller than said opening in said first protrusion.
