ABSTRACT:
A protective cover assembly for an outlet opening of an underfloor access housing is provided to prevent ingress through the outlet opening of a subsequently poured layer of floor fill, such as concrete. The assembly comprises a cup-shaped cap having a fence-like vertical extension detachably connected thereto. The assembly is enveloped by the floor fill and has an upper peripheral edge spaced below the upper surface of the floor fill by up to 1 inch (25.4 mm). A release coating interposed between the protective cover assembly and the floor fill facilitates breakout and removal of the overlying layer of floor fill.
