ABSTRACT:
The molded plastic rectangular shutter support housing and the mounting cover frame of the two-piece foundation ventilator are provided with connector devices for removably maintaining the shutter support housing and the mounting cover frame in assembled condition and for permitting disassembly of the mounting cover frame and the shutter support housing, if desired. The connecting devices include integrally molded clip members on the mounting cover frame with inwardly extending locking portions positioned in overlying engagement with integrally molded flanges of the shutter support housing to permit the shutter support housing to be removed from the mounting cover frame by sliding the shutter support housing longitudinally in one direction along the mounting cover frame and for assembling the two parts together by longitudinally sliding the shutter support housing in the opposite direction along the mounting cover frame. Locking arms are integrally molded with the shutter support housing and cooperate with the locking clip members to maintain the shutter support housing in assembled condition with the mounting cover frame.
