ABSTRACT:
An improved ventilator construction for use in masonry wall openings to ventilate interior spaces of a building, such as a basement or crawl space of a home, wherein the ventilator construction is particularly adapted for installation in an existing masonry wall opening without the need for concrete or mortar to retain the ventilator in place in the wall opening. The ventilator construction comprises a ventilator box having adjustable louvers for automatically controlling the access of air through the ventilator in response to changes in temperature, and a support frame for the ventilator box having a flanged peripheral opening for overlying the opening in the masonry wall. The support frame and ventilator box are connected to each other and to the masonry wall by means of depending ear-shaped connection elements on the ventilator box which have holes, or openings, which align with corresponding holes, or openings, in the side walls of the support frame whereby suitable fastening means, such as masonry nails, may be employed to connect the frame and ventilator box to the masonry wall itself.
