ABSTRACT:
The housing of a foundation ventilator has the usual front screen to protect the louvres within the housing, but the screen is part of a support frame used to mount the ventilator in an opening in a foundation wall. The support frame is frictionally retained in the opening by threaded bolts which can be easily loosened to gain access to the interior of the housing for cleaning or repair. It is not necessary to remove the ventilator from the wall. Similarly, if the support frame is damaged, it can be replaced without the expense of replacing the entire ventilator. The support frame has a connecting flange which seats within an extension of the housing to prevent relative lateral movement. Interlocking tabs and detents releasably attach the housing to the support frame with the screen in the support frame covering the front of the housing.
