Abstract
A skirt supports an access hatch at a predetermined height as the hatch is formed in concrete. The skirt can be permanently embedded in the concrete. The skirt includes a rigid frame defining a central opening, the frame has an inner surface and an outer surface opposite the inner surface. The frame defines a height between the upper edge and the lower edge. The height of the skirt is predetermined such that the combined height of the skirt and the hatch approximate the desired thickness of the concrete slab. The skirt may include an alignment tab extending from the frame at an angle with respect to the frame, with the alignment tab extending above the upper edge of the frame to guide the hatch into alignment with the upper edge of the frame as the hatch is moved into position on the skirt.
