ABSTRACT:
A preset access housing for use with metal cellular flooring units of the type placed in building floors, and which provide generally parallel enclosed cells separated by troughs. The housing spans between the confronting webs of two of the cells and has side walls depending into the region between the cells to enclose a trough space. A connection formed in part from portions of the end walls of the housing and in part by slots in the generally vertically webs of the cells, connects the housing to the flooring unit. Deflectible means associated with the side walls of the housing, engage a surface of the flooring unit in the region between the cells, are deflected, and urge the housing upwardly relative to the flooring unit thereby to retain the connection between the housing and the flooring unit. The upward biasing of the housing by the deflectible side wall portions, accommodates variations in the positions of the slots relative to the crests of the two cells, which variations may occur during roll forming of the upper sheet of the flooring unit.
